crash in rbuild creating vcproj

[ich]

Hello list,

I'm new here, so at first I'd like to greet everyone ;)

second: I had some problems running rbuild on WinXP SP2
self compiled with msvc 8.0 (Express) to produce .vcproj files.

I've found the problem in vcprojmaker.cpp and another thing, which
prevents me from building rbuild in genguid.cpp and I would like to
contribute a patch.

Kind regards,
Michael Sprauer
