+Subject: [PATCH 1/1] Include config.h in various files before any other
+ include statements
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is an indirect way to fix a compilation failure with musl
+libc. Glibc includes sys/stat.h as part of stdlib.h[1], which
+eventually typedefs dev_t[2]. Musl libc doesn't seem to pull that in
+like glibc does. The header file ext2fs.h uses dev_t in some of its
+function signatures[3], but the inclusion of sys/types.h is guarded by
+the macro `#ifdef HAVE_SYS_TYPES_H`[4].
+
+So every time ext4magic tries to include ext2fs.h while building with musl, it fails with:
+
+```
+In file included from hard_link_stack.h:23,
+from hard_link_stack.c:25:
+/usr/include/ext2fs/ext2fs.h:1402:39: error: unknown type name 'dev_t'; did you mean 'div_t'?
+1402 | extern char *ext2fs_find_block_device(dev_t device);
+|                                       ^~~~~
+|                                       div_t
+/usr/include/ext2fs/ext2fs.h:1822:62: error: unknown type name 'mode_t'
+1822 | extern int ext2fs_open_file(const char *pathname, int flags, mode_t mode);
+|                                                              ^~~~~~
+make[2]: *** [Makefile:467: ext4magic-hard_link_stack.o] Error 1
+```
+
+Autoconf actually declares HAVE_SYS_TYPES_H during ext4magic build, we
+just need to include config.h in the relevant C files so that the
+macro propagates. The alternative would be to pass -DHAVE_SYS_TYPES_H
+to gcc but that solution seems more of a hack compared to including
+config.h as it's meant to be included.
