Why not? The only thing I see that cl doesn't like the -mthreads flag
which is issued by --cxxflags. Here's what I get without wx-config.

%cl.exe -I/usr/local/lib/wx/include/msw-ansi-debug-2.8
-I/usr/local/include/wx- 2.8 -D__WXDEBUG__ -DWXUSINGDLL -D__WXMSW__
-mthreads pinky.cpp

That is, the same thing.

The difference between the two is the -mthreads flag. Can you explain
what the -mthreads does if you know? Reading

    http://ecos.sourceware.org/ml/pthreads-win32/1999/msg00120.html

it seems that EH needs a thread helper. I'll ask that in proper place.
