I spent today playing with the pc386 BSP. Downloaded the cd-working
toolchain (at first, I spent 2 hours in configure-hell because I had 
installed the toolchain from the snapshot area - everything got 
installed under /opt/gnucross. The wonderful 'configure' "tool" couldn't 
handle this [at least not when I followed the instructions in 
README.configure] - and I'm not exactly a beginner...). Then, I learned
GRUB, fixed the FXP network chip driver to recognize my card, built
CEXP for i386-rtems etc.

PROBLEMS:
1) Eventually, I got a linkage error: _fcntl_r is missing
    (cpukit/libcsupport/src/fcntl.c should implement it - fix attached
    with PR 340)

It's a good thing that my CEXP/system application tries to pull in 
almost the complete libc, librtemscpu, librtemsbsp libraries :-)

2) Another problem was that gcc-target-default.cfg does not
    add the LD_PATHS to the LDFLAGS anymore - is there a good reason
    for this (broke my application)? Hmm - After some research, I found
    that slightly different versions of 'gcc-target-default.cfg'
    are present in make and in c/src/make. Is this correct???

3) There might be some more issues on powerpc - I'll address this
    ASAP.

After supplying a dummy _fcntl_r (calling fcntl) IT WORKED, I'm happy 
and ready for a nap...
