Subject: bug#25381: sed 4.3: Test suite partially fails to compile when configured with --with-included-regex.
Date: Sat, 07 Jan 2017 06:29:25 +0100

This is another issue I noted when trying to port sed to FreeDOS using DJGPP
but it may be interesting for other OS too and can be reproduced with linux.
If I configure with the --with-included-regex option at least no one of the
bug-regex*.c files are linked with with libsed.a.  An inspection of the
makefile shows that entries like: testsuite_bug_regex*_DEPENDENCIES are
missing.  This is not he case for get-mb-cur-max.c and test-mbrtowc.c.
There may be more .c files where these specific dependecies are missing.
I have not inevstigated further.  The compilation of the required binaries
fail with the following error message:

depbase=`echo testsuite/bug-regex7.o | sed 's|[^/]*$|.deps/&|;s|\.[^.]*$||'` && \

if test $? = 0; then mv -f $depbase.Tpo $depbase.Po; \
  else rm -f $depbase.Tpo; false; fi
