As a followup to my prevoius post, apparently a g++ v2.7.2 program needs 
the above named library.  That's not surprising.  I'm curious what v2.5.4 
uses.  Anyway, turns out the problem with building gnu-libc is that a 
bunch of files use a function declaration format like:

__NORETURN void foo(arguments)....

The __NORETURN is what is blowing up gcc with a parse error.  I can't 
find mention of __NORETURN anywere in the system sources.  So what can I 
do about it?

Your help much appreciated.
