Yes, in-source builds should work and having Eclipse support that only part of 
the project tree are under versions control would be the best thing.
But maybe the problem is that if some part is under e.g. cvs, then other parts 
could be under other version control systems, which might be a problem for 
Eclipse.
Maybe being able to specifiy the source root or the version control root dir 
would help.
This should actually be not so hard, an additional entry in some project file 
and using this if it is present instead of the project dir.
Somebody feels like looking into the Eclipse/CDT sources ?
