[Bug c++/30348] New: '#define false FALSE' undefines '#define FALSE false'

["h8_spam at sonic dot net" <gcc-bugzilla at gcc dot gnu dot org>]

I ran into an issue where doing #define FALSE false followed by #define false
FALSE undefined the first FALSE which is not what I would expect.

Perhaps this is part of the standard, but in case not, I'm reporting it.

---------------------------------------------------------------------------

#define FALSE false
#define TRUE true

#ifndef true
#define true TRUE
#endif

#ifndef false
#define false FALSE
#endif

main() {
  bool test1 = FALSE;
  bool test2 = TRUE;
}

----------------------------------------------------------------------------
