+-# make depend makes the proper include file dependencies.  You _could_ run
+-# it on a sun4, but there's a bug in the SunOS version of sed that causes
+-# the all-important "cat makedep | sed -e 's/\.o/.d4o/p'" etc. line to
+-# not print the results to the stdout (but to keep pumping it through the
+-# edits.  The 'p' flag effectively does nothing). To avoid this I have
+-# replaced the 'p' flag by the 'w file' flag in sed.
