The width of wchar_t is allowed to be of the same width as long,
according to standards. The return type of mbscasecmp is int though.
On amd64 with a 32 bit int, this means that mbscasecmp can return
zero (indicating that strings are equal) even though the input
strings differ.
No known system exists that could trigger this.

There is a reason that I picked this one, annotation will help.
