The wcscat() function shall append a copy of the wide-character
string pointed to by ws2 (including the
terminating null wide-character code) to the end of the wide-character
string pointed to by ws1. The initial wide-character
code of ws2 shall overwrite the null wide-character code at
the end of ws1. If copying takes place between objects
that overlap, the behavior is undefined.
The wcscat() function shall return ws1; no return value
is reserved to indicate an error.
No errors are defined.
