These rules are a bit problematic.  They requires that the cc files
exist in the build dir.  I tweaked the build mechanism in the Cygwin
dir creating version.o so that the deps always work, and I simplified
the above ruleset to a single rule just requesting the object files.

I just created a new developer snapshot which picks up this change.


Thanks,
Corinna
