Thanks for your reply.

I put gmp/config.log at

http://www.math.purdue.edu/~lucier/bugzilla/10/gmp-config.log

and the build log (which is a bit confusing, I did a "make -j 6  
bootstrap > build.log" and then "make bootstrap >>& build.log" (in  
tcsh) to get a clearer message of the error at the end of the log) at

http://www.math.purdue.edu/~lucier/bugzilla/10/build.log

I tried building gcc like this on another machine, and it gets more  
confusing, at least to me.  When I put gmp-4.2.4 or gmp-4.3.0 in-tree  
on RHEL 5 with

leibniz-4% uname -a
Linux leibniz.math.purdue.edu 2.6.18-128.1.16.el5xen #1 SMP Fri Jun  
26 11:10:46 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

it works; when I put either in-tree on Ubuntu 9.04 with

heine:~/programs/gcc/objdirs/mainline> uname -a
Linux heine.math.purdue.edu 2.6.28-13-generic #45-Ubuntu SMP Tue Jun  
30 22:12:12 UTC 2009 x86_64 GNU/Linux

it fails.
