OK, trying the __attribute__ stuff doesn't seem to work for me:
f12.h:3: warning: `visibility' attribute directive ignored
f12.h:4: warning: `visibility' attribute directive ignored
Where f12.h looks like:
---------------------------
#define INTERNAL __attribute__((visibility("hidden")))
extern void foo1( void ) INTERNAL;
extern void foo2( void ) INTERNAL;
extern void glfoo2( void );
---------------------------
And gcc -v gives:
gcc version 2.96 20000731 (Mandrake Linux 8.1 2.96-0.62mdk)
Is this a versions thing or am I screwing up elsewhere?
