How to distinguish MYDEF and MYDEF() with #ifdef

[Wesley Smith]

Or why not

#define _OLD_MYDEF MYDEF
#undef MYDEF

#define MYDEF //<-- yours

//use it


#undef MYDEF

#define MYDEF _OLD_MYDEF

which is untested and a bit ridiculous but should work.  If you don't
need MYDEF anymore in this particular file then you can leave off the
bottom section.
