UnixWare 7 g++ testsuite Failures: Ugly std_cwchar.h patch.

[rbrown64@csc.com.au]

This ugly patch addresses part of what Robert Lipe describes as
"the ancient problem in libstdc++ of running configure with
liberal flags and then turning on "-ansi" (thereby potentially reducing
the available namespace to that of a conforming implementation) later on
during the testsuite run.".
Note, it has NOT yet survived a full bootstrap - just a make check-c++ .
It won't help if <wchar.h> is included before the C++ headers.

Is it worth it just to silence testsuite failures?

     * include/c_std/bits/std_cwchar.h: #undef __STRICT_ANSI__ before
     including <wchar.h> to avoid warnings for v{f,s,}wscanf on UnixWare 7.
