I have been struggling with this issue, and now that I have
successfully built GCC I thought I would share my results. Hopefully
it can help someone better versed in autotools to improve the build
of GCC with GMP/MPFR.
For reference, a few older threads I've found:

You do mean gcc 4.3 right (either a snapshot, or from svn)?
Since you're running on x86_64, do you know that the libraries are
the correct bitness (running 'file' on the mpfr and gmp libraries
will tell). By default gcc on x86_64 will build 64-bit, but
libraries in /usr/local/lib should on

MPFR should not have _anything_ to do with any gcc prior to 4.x. Where did you
get gcc 3.4? A tarball from a gnu mirror or somewhere else? I think either t

What is the exact file name and URL? I will download the same tarball and try
to build it on my fc6 box.

This is checking out the latest trunk, not version 3.4. The last argument only
changes the name of the directory name on your local machine. The 'svn://' is
what specifies the tag (in
Having searched in bugzilla and asked on gcc-help to no avail ...
gcc --coverage appears to be broken on x86_64 in gcc 4.1.1 on FC6 (works fine
with Trunk). I'm almost certain that this is a known issue, but cannot find a
reference in Bugzilla.
Could someone please give me a pointer to the bug?

Per http://gcc.gnu.org/ml/gcc/2006-10/msg00141.html it is possible to
build GMP/MPFR in the local tree with the current Trunk. This build
method may ease issues with building gcc. Would it be possible to
document this for 4.3?
Thanks,

Actually, for gets, and essentially the entire stdio.h, Visual Studio 2005
generates:
warning C4996: 'gets': This function or variable may be unsafe. Consider
using gets_s
