Of course!
It was not really hard to get it going. The first problem i ran into
was that on my OSX box the 'readlink -f .' would not do the obvious.
I replaced it with `pwd`:
--------8<--------
$ svn diff build-mingw32ce.sh
Index: build-mingw32ce.sh

--- build-mingw32ce.sh (Revision 916)

+export PREFIX=${BASE_DIRECTORY}/opt/mingw32ce
if [ $# -lt 1 ] ; then
BUILD_OPT="all"

I also decided to use another prefix dir, but that is not really
important. I made this changes in "build-mingw32ce.sh" and in "build-
cegcc.sh".

After that changes i was able to start both build scripts without
parameters. Unfortunately gdb does not build using "build-mingw32ce.sh":
.../cegcc/src/gdb/gdb/exceptions.h:165: error: parse error before
‘va_list’
make[2]: *** [gdb.o] Error 1
make[1]: *** [all-gdb] Error 2
make: *** [all] Error 2
"build-cegcc.sh" runs *perfectly*well* without any complaints!!!

It has; But unfortunately it is somewhat tricky to cross build it, it
needs 'python' for bootstrapping. I will try to find out how i can
use an existing python interpreter to handle bootstrapping of an
other python interpreter that is being built but never 'run'.

PyGame is the thing i want to run; I got PythonCE running, but i can
not import pygame with it...

That SOLVED the problems :-)
And still I hope i can make pygame and gdb run...
