Yes, I assumed pg_ctl would have such issues.  pg_dumpall has them as
well calling pg_dump.

Here is a strange idea that I am looking for someone to check. According
to someone, Win32 system just strips off the first and last quotes, and
that is why it is failing.  Try adding a quote to the beginning and end
of the system string, and leave the existing quote intact.  That might
fix is and if it does I can add this to CVS.
