This is the approach I took before but for some reason you didn't accept the
patch in process.c related to starting unix lib type applications. The
work-around was to change to the lib directory locate the pwd chdir back,
then start the lib using the actual path.rather than the link. There may be
another way to find the target directory of a link more elegantly but I don't
know it. Anyway, I maintained this delta but it has now expired with the
changes in process.c and need to be rewritten anyway.
While this course of action (eliminating the colon) is prone to some
compatibility issues in the short term I think in the longer term it will
enhance portability and compatibility and therefore reduce the maintenance
cost of "dosdevices" going forward (And perhaps solve a few latent issues
for non-linux OSen)
