"build_alias" trouble under Cygwin when use "--disable-networking"

I haven't noticed that restarting the Cygwin shell helps, but shutting down 
other programs and not using the computer for anything else while it builds 
definitely does.  I normally keep a lot of programs open (several Cygwin 
shells, CodeWright, web browser, Acrobat viewer, etc) and have other things 
going (downloads, printing, etc.) while I wait for long compiles.  I have 
built other large projects under Cygwin with my computer loaded heavily 
without any trouble, but when rebuilding RTEMS, I have started shutting 
everything else down and using a different computer while it builds.  If I 
don't shut everything else down, it will lock up or fail with the 
build_alias message about half of the time.

Even without any other programs running, I was having trouble with the 
command line

   ../rtems-4.6.0pre5/configure --target=m68k-rtems \
       --enable-rtemsbsp=csb360 --disable-networking

I had much better results with

   ../rtems-4.6.0pre5/configure --disable-networking \
            --target=m68k-rtems --enable-rtemsbsp=csb360

I don't know why changing the order of the command line options should make 
a difference, but it does on my system (IIRC others have mentioned similar 
things on Cygwin).  It seems like there is a stability problem under 
Cygwin, at least when compiling RTEMS.  I don't have any idea how to go 
about tracking it down.
