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

I do. I have tried compiling a more modern system on it, and run into
some considerable (But not insuperable) difficulties. What they did,
however, was to prevent automation of the process, as one had to check
each command did what it was supposed to. Some did not. I ran that as
far as missing options, in ordinary programs, but never bothered after
that.

Nice try, Paul, but no cigar. 

Connor and I were talking of doing this on an rhel i86 box under linux. 
I made no claim with regard to anything else. 'Another (unspecified)
enterprise OS' is not what we want. Neither do we want to see gmake,
sun, sparc, or solaris. It's smoke and mirrors, Mandrake :-). I still
claim to be a _user_, but I'm not that green :-).

File one on the configure script if you didn't have binutils-2.15.91 or
later, which is not, incidentally, a standard version of rhel.
