I suspect this is because Cygwin does not support the /proc/fd magic
filesystem or its equivalent.

Indeed, if I remove PATH_DEV_FD from config.h and recompile, I can no
longer reproduce the error.

There has to be something more going on, though, because moving the call
that closes the /proc/fd descriptors from exec.c into jobs.c:deletefilelist
does not resolve the problem.
