That's correct. And even system headers do it like this, probably
there's some magic in the background to work with ns-dragndrop and the likes.

Mario@shodan:/usr/include$ grep -r " environ " *
X11/Xw32defs.h:#  define environ     _environ
apache2/modperl_perl_includes.h:#   define environ (*_NSGetEnviron())
architecture/i386/fpu.h: *     #define environ (*_NSGetEnviron())

That would be

#ifdef __APPLE__


Thanks,
