Alexandre,
The winspool.drv issue is a lot more serious than the in-tree execution. This one screws things up badly for the PuTTY build system. Should we modify winebuild to try to link with winspool.drv, and if that fails with winspool.dll when -lwinspool is given? (or the other way around, I don't know)
I'd really appreciate help on this one, so I can send the patch out.
