Consider the following code fragment:

typedef char *String;
const char *str1;
const String str2;

Are str1 and str2 supposed to be the same type?

I've been trying to code some X stuff in C++ .
Some pointers to functions have been giving me fits because their argument
lists differ in just that way.  The compiler says they're different.

Nope :  const char * is const char *,
while const String is char * const.

No. "const String" =3D=3D "String const" =3D=3D "char *const".

No. "str1" is of type "const char*", "str2" is of type "char* const".

Thanks, it's what I suspected.
