[ILUG] Can anyone see any reason why a customer would need to compile a new compiler?

Hmm, maybe - take it as good-humoured though.

I don't have that particular 'enterprise' OS available, but I can try 
another..

Hmm, well would just 'configure && make' be acceptable?:

$ wget http://ftp.heanet.ie/pub/gnu/gcc/gcc-4.1.0/gcc-core-4.1.0.tar.bz2
$ gtar -xjf gcc-core-4.1.0.tar.bz2 && cd gcc-4.1.0
$ (./configure && time nice -n 10 gmake -j48) > /dev/null

$ gmake DESTDIR=/tmp/gcc-inst INSTALL=ginstall install > /dev/null

$ echo -e '#include <stdio.h>\nint main (void) { \
printf("hello world\\n"); }' > test.c && \
  /tmp/gcc-inst/usr/local/bin/gcc  -o ./test -O -lc ./test.c && ./test
hello world

NB: the compile time is slightly slow due to various 'very far away' 
NFS mounts I have in my PATH.

Now, I didn't actually check whether or not that machine had the 
latest Linux kernel headers installed, so I can't guarantee it didn't 
- however if it did, it would surprise me... ;)

So I think I can hold off on filing a GCC bug for now.
