--- Comment #1 from Tom Tromey <tromey at gcc dot gnu.org> ---
Also, note what happens if one changes the body of the function:
extern void *allocate (int);
#define my_alloc(X) allocate (X)
int *alloc_int(void)
{
return my_alloc(sizeof (int));
}
barimba. gcc --syntax-only -Wc++-compat r.c
r.c: In function ‘alloc_int’:
r.c:7:3: warning: request for implicit conversion from ‘void *’ to ‘int *’ not
permitted in C++ [-Wc++-compat]
return my_alloc(sizeof (int));
^
Now there's no mention of the macro at all.
