macosx extern inline problem

[Jay K]

Marc, good point:
 
$ echo | gcc  -Wp,-dM -E - | grep APP
#define __APPLE_CC__ 5493
#define __APPLE__ 1

 
However just simply:
 
#ifdef __GNUC__
#define WHATEVER_GMP_INLINE extern __inline__
#define WHATEVER_GMP_PROTOTYPES 0
#endif
 
will presumably just work with many gcc versions, FSF, Apple, old, new.
?
 
A little less code, works more, just as well?
(Maybe put in a separate #ifdef for cygwin, since the comment implies it is needed for it?)
