[Bug c++/24559] New: Incorrect definition of wcspbrk in cwchar

[david dot moore at intel dot com]

According to the C++ standard the declarations of wcspbrk should take two cont
pointers or a (non-const pointer and a const pointer (in that order):

The actual declarations as if gcc 4.0 and apparently since introduction of the
second declaration take either two const pointers or two non-const pointers:

const wchar_t* wcspbrk(const wchar_t* s1, const wchar_t* s2);
wchar_t* wcspbrk( wchar_t* s1, const wchar_t* s2);

As a result the following (rather artificial) program does not compile when it
should:

#include <cwchar>

typedef wchar_t* (*pf)(wchar_t *, const wchar_t*);

int main() {
   pf p1 = std::wcspbrk; // should compile
   return 0;
}
