Apologies if mails on this are sporadic, but I can only test this at
college. Would reinstalling gcc solve the corrupted symlink problem as I
have already tried that and I still get the same error. A process is
actually being spawned (the as.exe process) so it doesn't sound like the
symlinks are corrupted.
Do you (Chris) or anyone else have any good tips I can use to debug this? I
can't compile the Cygwin DLL on the college machines (because of this
problem) so I can't build a debug version. Also the processes that are
crashing don't seem to reach the Cygwin DLL initialisation stage anyway. I
can supply any further information you need to debug this, but I need to
know what would be helpful.

Chris
