mpfr-related link errors

[Bob Walters]

A recent change (builtins.c mpfr work) seems to be giving me link  
errors.  I'm trying to get back on track.  Have done an svn update,  
followed by a reconfigure (needed) and recompile.

Thought the issue was with the version of mpfr I was using, so I  
upgraded from mprfr-2.3.0 to 2.3.2, and this did get rid of a compile  
error I was having on builtins.c.  I have added mpfr to the gcc source  
directory, and done a make distclean and attempting to rebuild.  I'm  
still getting the link error shown below.  Any help is appreciated.

Build environment is MacOS 10.5.5...
Here's what I've been configuring with:
