Yeah, it looks like:-) but I was wrong... I removed this check and ran
into troubles. The Macro __GLIBC_HAVE_LONG_LONG must not be defined
with ccc. So this check is totally ok! It has nothing to do with
"long long". Sorry... I was searching for the reason why I couldn't
compile python with ccc.
After some time I found it! The attached patch solves the problem. Now
I'm running python 2.3 compiled with ccc:-)

Hehe, no! 
This seems not to be the right place neither. I think this is useless
anyway. The right place to fix it is in "create-comp-config.sh". I tried
to change it but it seems that a shell-script and regex guru is
needed;-) The same should be changed by cxx (preventing).

With these two fixes, I'm able to compile a lot more packages with the
compaq compiler.


Oh, while we are at it. What do you think if we move the libots libs to
/lib instead of /usr/lib ?

Lastly, I ran into troubles as I compiled gawk with ccc. 
Could you imagine what happens? I've made a RAID array with several
partitions on it. One partition was /usr.
gawk is needed in the init scripts, but libots.so is located in
/usr/lib, which is not mounted yet. Too bad.
