Actually as string literals are defined as specifying an array of character constants,
a "const char *" type seems most appropriate, which is why a write to a string literal
is undefined.

But agree that GCC should not generate a warning that the types differ in signness
when initializing a signed or unsigned char * with a string literal, as the types are
defined as being compatible; but should generate a warning that a "const char *" is
being assigned to a non-const "char *".
