--#  AC_LIBTOOL_DLOPEN
--#
--#       Enable checking for dlopen support. This macro should be used if the
--#       package makes use of the '-dlopen' and '-dlpreopen' flags, otherwise
--#       libtool will assume that the system does not support dlopening. The
--#       macro must be called before AC_PROG_LIBTOOL.

--# -----------------------------------------------------------------------------
--#
--#  AC_LIBTOOL_WIN32_DLL
--#
--#       This macro should be used if the package has been ported to build
--#       clean dlls on win32 platforms. Usually this means that any library
--#       data items are exported with __declspec(dllexport) and imported with
--#       __declspec(dllimport). If this macro is not used, libtool will assume
--#       that the package libraries are not dll clean and will build only static
--#       libraries on win32 hosts.
--#
--#       This macro must be called before AC_PROG_LIBTOOL, and provision must
--#       be made to pass '-no-undefined' to libtool in link mode from the package
--#       Makefile. Naturally, if you pass '-no-undefined', you must ensure that
--#       all the library symbols really are defined at link time!

--# -----------------------------------------------------------------------------
--#  AC_PROG_LIBTOOL
--#
--#       Add support for the '--enable-shared' and '--disable-shared'
--#       configure flags. By default, this macro turns on shared libraries
--#       if they are available, and also enables static libraries if they
--#       don't conflict with the shared libraries. You can modify these
--#       defaults by calling either the AC_DISABLE_SHARED or AC_DISABLE_STATIC
--#       macros.
--#
--#       Hercules REQUIRES shared libraries (i.e. DLLs), so we do indeed use
--#       the AC_DISABLE_STATIC macro above.
--#

--#
--#  AC_LIB_LTDL
--#
--#       Even though libltdl is installed together with libtool, you may wish
--#       to include libltdl in the distribution of your package, for the convenience
--#       of users of your package that don't have libtool or libltdl installed.
--#
--#       The most simplistic way to add libltdl to your package is to copy the
--#       source files, 'ltdl.c' and 'ltdl.h', to a source directory withing your
--#       package and to build and link them along with the rest of your sources.
--#
--#       To do this, you must add a call to the 'AC_LIB_LTDL' macro to your package's
--#       'configure.in' to perform the required configure time checks in order that
--#       'ltdl.o' is built correctly.
--#
--#       This method does have its problems though: if you try to link the package
--#       binaries with an installed libltdl, or a library which depends on libltdl,
--#       you may have problems with duplicate symbol definitions.
--#
--#       In order to enable this flavor of libltdl, you should add the line
--#       'AC_LIBLTDL_CONVENIENCE' to your `configure.in', before 'AC_PROG_LIBTOOL'.
--#
--#       In order to select the installable version of libltdl, you should add a
--#       call of the macro 'AC_LIBLTDL_INSTALLABLE' to your 'configure.in' before
--#       'AC_PROG_LIBTOOL'. This macro will check whether libltdl is already
--#       installed and, if not, request the libltdl embedded in your package to be
--#       built and installed.
--#
--#       Whatever macro you use, it is up to you to ensure that your 'configure.in'
--#       will configure libltdl, using 'AC_CONFIG_SUBDIRS', and that your 'Makefile's
--#       will start sub-makes within libltdl's directory, using automake's SUBDIRS,
--#       for example. Both macros define the shell variables LIBLTDL, to the link flag
--#       that you should use to link with libltdl, and LTDLINCL, to the preprocessor
--#       flag that you should use to compile with programs that include 'ltdl.h'. It
--#       is up to you to use 'AC_SUBST' to ensure that this variable will be available
--#       in 'Makefile's, or add them to variables that are 'AC_SUBST'ed by default,
--#       such as LIBS and CPPFLAGS.
--#
--#       So, when you want to link a program with libltdl, be it a convenience,
--#       installed or installable library, just compile with '$(LTDLINCL)' and link
--#       it with '$(LIBLTDL)', using libtool.
--#
--#       You should probably also add 'AC_LIBTOOL_DLOPEN' to your 'configure.in' before
--#       'AC_PROG_LIBTOOL', otherwise libtool will assume no dlopening mechanism is
--#       supported, and revert to dlpreopening, which is probably not what you want.
--#
--#       The following example shows you how to embed the convenience libltdl
--#       in your package. In order to use the installable variant just replace
--#       'AC_LIBLTDL_CONVENIENCE' with 'AC_LIBLTDL_INSTALLABLE'. We assume that libltdl
--#       was embedded using 'libtoolize --ltdl':
--#
--#           configure.in:
--#
--#               ...
--#               dnl Enable building of the convenience library
--#               dnl and set LIBLTDL accordingly
--#               AC_LIBLTDL_CONVENIENCE
--#               dnl Substitute LTDLINCL and LIBLTDL in the Makefiles
--#               AC_SUBST(LTDLINCL)
--#               AC_SUBST(LIBLTDL)
--#               dnl Check for dlopen support
--#               AC_LIBTOOL_DLOPEN
--#               dnl Configure libtool
--#               AC_PROG_LIBTOOL
--#               dnl Configure libltdl
--#               AC_CONFIG_SUBDIRS(libltdl)
--#               ...
--#
--#           Makefile.am:
--#
--#               ...
--#               SUBDIRS = libltdl
--#
--#               INCLUDES = $(LTDLINCL)

--#  AC_LIB_LTDL
--#
--#       Even though libltdl is installed together with libtool, you may wish
--#       to include libltdl in the distribution of your package, for the convenience
--#       of users of your package that don't have libtool or libltdl installed.
--#
--#       The most simplistic way to add libltdl to your package is to copy the
--#       source files, 'ltdl.c' and 'ltdl.h', to a source directory withing your
--#       package and to build and link them along with the rest of your sources.
--#
--#       To do this, you must add a call to the 'AC_LIB_LTDL' macro to your package's
--#       'configure.in' to perform the required configure time checks in order that
--#       'ltdl.o' is built correctly.
--#
--#       This method does have its problems though: if you try to link the package
--#       binaries with an installed libltdl, or a library which depends on libltdl,
--#       you may have problems with duplicate symbol definitions.
--#
--#       In order to enable this flavor of libltdl, you should add the line
--#       'AC_LIBLTDL_CONVENIENCE' to your `configure.in', before 'AC_PROG_LIBTOOL'.
--#
--#       In order to select the installable version of libltdl, you should add a
--#       call of the macro 'AC_LIBLTDL_INSTALLABLE' to your 'configure.in' before
--#       'AC_PROG_LIBTOOL'. This macro will check whether libltdl is already
--#       installed and, if not, request the libltdl embedded in your package to be
--#       built and installed.
--#
--#       Whatever macro you use, it is up to you to ensure that your 'configure.in'
--#       will configure libltdl, using 'AC_CONFIG_SUBDIRS', and that your 'Makefile's
--#       will start sub-makes within libltdl's directory, using automake's SUBDIRS,
--#       for example. Both macros define the shell variables LIBLTDL, to the link flag
--#       that you should use to link with libltdl, and LTDLINCL, to the preprocessor
--#       flag that you should use to compile with programs that include 'ltdl.h'. It
--#       is up to you to use 'AC_SUBST' to ensure that this variable will be available
--#       in 'Makefile's, or add them to variables that are 'AC_SUBST'ed by default,
--#       such as LIBS and CPPFLAGS.
--#
--#       So, when you want to link a program with libltdl, be it a convenience,
--#       installed or installable library, just compile with '$(LTDLINCL)' and link
--#       it with '$(LIBLTDL)', using libtool.
--#
--#       You should probably also add 'AC_LIBTOOL_DLOPEN' to your 'configure.in' before
--#       'AC_PROG_LIBTOOL', otherwise libtool will assume no dlopening mechanism is
--#       supported, and revert to dlpreopening, which is probably not what you want.
--#
--#       The following example shows you how to embed the convenience libltdl
--#       in your package. In order to use the installable variant just replace
--#       'AC_LIBLTDL_CONVENIENCE' with 'AC_LIBLTDL_INSTALLABLE'. We assume that libltdl
--#       was embedded using 'libtoolize --ltdl':
--#
--#           configure.in:
--#
--#               ...
--#               dnl Enable building of the convenience library
--#               dnl and set LIBLTDL accordingly
--#               AC_LIBLTDL_CONVENIENCE
--#               dnl Substitute LTDLINCL and LIBLTDL in the Makefiles
--#               AC_SUBST(LTDLINCL)
