That's a problem which can be solved almost as easily as with the 
macro solutions:

ctype.h:

#define EXTERN_INLINE extern inline
#include <inlines/isalpha.ha>
#include <inlines/isalnum.ha>
/* ... */


src/libc/ansi/ctype/isalpha.c:
#define EXTERN_INLINE /* nothing */
#include <inlines/isalpha.ha>
