Thanks for the prompt and helpful replies Paul, Blake, and Laurent.
As root, `ulimit -S -s 131072'  allowed `gmp-chudnovsky 100000000' to 
complete.

I will try recompiling with the enable-alloca flags, as default user 
stack is 8192K.
I'm using gmp-4.2.1 but haven't done any patching, as no test returned 
error.
I guess the x86-fat.diff patch can't hurt anything.  I need the 
compiling practice as
I'm not yet comfortable with the `new' automake, and its many options.
 
Thanks again,
Richard
