A more generic approach could be:

In the file "config.mak.uname": Define a variable in the Darwin section like this
NO_EXT_ENVIRON = UnfortunatelyYes

In "Makefile", pick it up, and convert it into a compiler option:
ifdef NO_EXT_ENVIRON
	BASIC_CFLAGS += -DNO_EXT_ENVIRON
endif

And in "git-compat-util.h", add these lines "at a good place":
#ifdef NO_EXT_ENVIRON
extern char **environ;
#endif

This will allow other OS to use the NO_EXT_ENVIRON when needed,.

Thanks for working on this.
