More minor issues found while building libstdc++-v3 in gcc mainline for FreeBSD (with patch) 1/3

[Steven King]

I've also encountered this problem under linux, but I think the problem is some
sort of breakage on the configuration;  the correct specialized
char_traits<wchar_t> is #ifdef by _GLIBCPP_USE_WCHAR_T, which appearently isnt
being defined so that the template char_traits definition is used instead for
wchar_t.
