It should be set by default and those that don't have it, should (have to)
disable it.
In Makefile:
ifndef NO_STRING_H
COMPAT_CFLAGS += -DHAVE_STRING_H=1 # needed in compat/fnmatch/fnmatch.c
endif

Valid point, but...

Hmm, well, why then doesn't git-compat.util.h use the same mechanism? (and no
,it should not!)
I guess because as of now nobody ever tried to port git to a platform that
doesn't have string.h.
string.h is C89 ANSI/ISO standard (and was part of even the earliest K&C C), in
place since more than 22 years now! It may not be
available on embedded platforms, but those won't be able to run git anyway I'd
guess.
Newer version of gnulib's fnmatch.c don't use this anymore, git's is from 99,
according to the Copyright:
Copyright (C) 1991, 92, 93, 96, 97, 98, 99
The current gnulib one shows:
Copyright (C) 1991-1993, 1996-2007, 2009-2012
Time to upgrade, if you'd ask me...
Same may go for poll.c BTW
Bye, Jojo
