Is there anything I can do to fix this? Compiling from Windows9x/ME
might help?

Every command?  For me I get the illegal operation
messages every time octave calls fork().  Fork is
very slow (it makes a copy of the process rather
than being copy on write) which also explains the

Instead of fork we should be using spawn.  Windows
has a pipe operation, and I tried linking against that,
but it didn't work for more complicated pipes.

system() is called for help and for the pager.  If you
don't use help, and you set page_screen_output=0,
you should be okay.  It is annoying waiting for it
to start up though.

The fork() problem is part of the reason compiles
take so long on cygwin.
