MD-    Looks to me that you are trying exactly the config we're trying to
use. I've had
MD- nothing but problems with RTEMS/cygwin. If you get a configuration
working I'd be REALLY 
MD- REALLY interested to know what versions of RTEMS and the tools you used
(and any 
MD- patches).

I'll put a summary together.

I got much further when I rebuilt my tools and RTEMS-4.6.2 with couple of
minor changes in my scripts:

 1. I disabled NLS for gcc (probably not an issue),
 2. I did not '--enable-shared' for gcc (this wasn't available to build for
PPC anyway),
 3. I enabled 'version-specific-runtime-libs' (probably not an issue yet),
and
 4. For the RTEMS build I specified '--prefix=<my_toolchain_prefix>' (which
_was_ probably
    the real key).

(I got this lead by installing the powerpc-rtems tool binaries on a Linux
box and running:
 '$ powerpc-rtems-gcc -v'.)

NEXT PROBLEM:
All PPC BSP targets now build and install successfully _except_ MVMV2307,
mcp750, and mtx603e. These targets all fail to build 'tests/tmtests/tm27',
but they all build OK if this subdirectory is removed from the build list!

The problems all seem to arise from one included file: <bsp.h>, giving
errors such as:

>>>> QUESTION: Does this ring a bell for anyone?

MD-    The weirdest problem I've had is that gcc builds ok but takes 3
hours! it then won't 
MD- compile the powerpc-rtems bsp with various error messages.

Yes - 'leisurely' is the kindest word I would use. No way I could afford to
use this for production!
