Normally I'd blame inode generation on remote drives, but that's not it
since I've turned off inode based path lookup optimization in gcc.

It does look like a problem with Cygwin interaction with SunLink (I know
nothing of this software). Now that we know where the problem lies, we
should try to isolate it by writing the shortest possible testcase. Maybe
a problem with `stat' on SunLink server?

I suppose the strace output may be a good place to start. It's going to be
large, so do compress the output using gzip before posting. Hopefully the
Cygwin gurus can take over and solve this mystery.

I'm gone till early next week, so can't be of any help till then.

Regards,
Mumit
