Yikes.

This is now in 'master', but I wonder if people are getting
compilation errors because of this change.  I do.

It introduces a call to setlocale() without causing <locale.h> to be
included, and runs afoul of -Wimplicit-function-declaration.

Other call sites of setlocale() are in gettext.c, which does include
the header at the beginning.

I really do not like a conditional inclusion of system header files
inside any *.c file, but here is a minimum emergency fix-up I am
running with today.  It should go to somewhere in git-compat-util.h.

Somebody care to throw a tested fix-up patch at me?

Thanks.
