I don't know about this problem here, but wouldn't "new (std::nothrow)"
be the correct solution anyway?

IIRC, gcc assumes that the standard new always succeeds if it doesn't
throw an exception (which it can't in this case due to -fno-exceptions)
and calls the constructor without checking the return value from new. So
checking for curr_stream == NULL in fopen.cxx is useless because calling
Cyg_StdioStream's constructor with a NULL this pointer will most likely
already have caused a crash.
