[bug #66518] [libgroff] stop doing what gnulib can do for us

[Collin Funk]

Follow-up Comment #1, bug #66518 (group groff):

Hi Branden,

I can try to help with some of this. I've attached a patch to use Gnulib for
strcasecmp and strncasecmp.

This patch is simple since the Gnulib module doesn't depend on much.
Therefore, we don't need to link programs to anything (other than libgnu.a and
libgroff.a).


$ gnulib-tool --extract-recursive-link-directive strcase
$


Others will require system libraries and require <program>_LDADD variables to
be updated.

For example:


$ gnulib-tool --extract-recursive-link-directive mkstemp
$(CLOCK_TIME_LIB)
$(GETRANDOM_LIB)


On some systems extra libraries are needed for clock_gettime and getrandom, so
all programs using mkstemp will need those added to <program>_LDADD.

The most time-consuming part will be updating those.

Happy to help with the rest if you don't get to it first. :)
