Ummm... no.  Nor do I believe that the inline c language spec calls for it.


Yes.  First, drop the use of external inlines.

Second, map out a strategy that will work across inline and non-inlining
compilers.  Map out a strategy for building said fn's as exports as well
as inlines.

The typical win32 model on this stuff is;


   #ifndef INLINE
   void EXPORT somefn(void);
   void INLINE somefn(void)

Now #define INLINE inline before including foo.h and you have the
inlined functions.

If you write a simple module that is linked in;


   /* Toggle inline to include function bodies, but use
    * the EXPORT keywords instead to compile as fn's.
   #define INLINE EXPORT
   #include "foo.h"

You now have both flavors.

Question of the hour is, WTF?  It's inline or it's not.  Why add the additional
complexity?  And remember that inlining will clobber us on binary compatibility
on otherwise perfectly safe changes to the internal guts of opaque structures.
