The check for _WCHAR_T is redundant and potentially wrong (if autoconf didn't
detect wchar_t and _WCHAR_T is still defined, something is amiss. It's probably
better to terminate with a compiler error then).
That said, if upstream has accepted the patch as is, it's better to keep it
this way.

Why is this needed? I can't see how this could ever lead to something good...
But I guess that's upstream's problem.
