Good point, I'd not realized that. 7.1p3 right?
However, that doesn't help. I can still expect to be able to compile
the following code at function scope:
char * (*p) (char *);
p = basename;
which one cannot with GCC in strict mode if the prototype of basename
changes. So I still maintain we have to retain prototype compatibility
of any library header function.
