I did an email reply on the question but sources.redhat.com say that I am
spammer -- I did not look at it because it was from  @sources.redhat.com!

Short version the current GCC-CVS HEAD is working with -O3 -- so this
bug can be closed. 

Long version:

The current GCC-CVS HEAD can't bootstrap because of a error:
http://gcc.gnu.org/ml/gcc/2003-05/msg00971.html

I have bootstrap the GCC-CVS HEAD in the last months with -O3 (gcc-3.4)
and that is also my current bootstrap gcc/gnat compiler.

I can't create a compiler from the build description for GCC-3.2.3. I
try with a version from the current GCC-cvs (GCC) 3.4 20021228 and and
newer.  (experimental) It failed:
 
make[3]: Entering directory `/mnt/home3/lasj/Work/GCC/work/gcc/ada'
gcc -c -march=athlon -pipe -O2 -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic
-Wno-long-long    -W -Wall -gnatpg -gnata -I- -I.

fatal error: system.ads is incorrectly formatted

compilation abandoned
make[3]: *** [ada.o] Error 1

And when I tries with gnat-3.14p using ADAC= it will not create the ada
part. Is the instruction for creating the ada compiler right, last time
I bootstrap gcc-ada via gnat-3.xx was it quit complicated?
