Putting less empty lines in mails may also help.

Did you try look at the file in Modules/Platform like
http://public.kitware.com/cgi-bin/viewcvs.cgi/Modules/Platform/cl.cmake?revision=1.6&root=CMake&view=markup

It also uses /Fo and thus obviously sets this.
Each other compiler also fits as example.
