 I guess you need to compile wx with --disable-exceptions if you do it for
M. It would be nice if we could override wxUSE_EXCEPTIONS before including
wx headers but I don't think this works currently.

 The simplest would be to stop using -fno_exceptipns when building M, of
course...

Should I commit disabling -fno-exceptions (it helped to compile) or should
we wait until we can override wxUSE_EXCEPTIONS?
