[cvsnt] projecthandling for different platforms

[Sven.Fondel at np-gmbh.com]

hi,

We have one single sourcecode with preprocessortags for different
platforms.
The problem is, that we have codepieces which are relevant for all
platforms, and specific ones.
How to differntiate the tags when creating a tag for a platform, and
afterwards change things in the general part ?

How did you resolve this issue ? And what experiences did you make ?

THX in advance
