I was able to reproduce the same error with gcc 3.4.6.

The purpose of the test is to verify the conformance of the
<cwchar> header WRT namespace cleanliness (i.e., that symbols
like struct tm are defined in namespace std and not also in
the global scope). The test is designed to fail at runtime
(via assertions) rather than at compile time but it looks
like the implementation of the test (or maybe even its
design) is broken. In any case, the fact that the test
doesn't compile suggests there is a problem with the header.
The compilation errors for the simple program below confirm
this. Can you open an issue for this problem and reference
this thread in the archive in the issue?

$ cat t.cpp && nice make t
#include <cwchar>

int main ()
{
     std::tm tmb = { 0 };
}

gcc -c -I/amd/devco/sebor/stdcxx/include/ansi -D_RWSTDDEBUG
