I entirely agree that all the char business in C is messy enough to justify separate warning switch(es) in GCC.
However, I still insist that the problem with the code:
void foo(char *c); unsigned char *u; signed char *s; ... foo(u); foo(s);
is not (only) in signedness, as neither 'u' nor 's' has compatible type with the "char*", no matter what is the sign of "char", so if one cares about type safety he needs warnings on both invocations of foo().
