I did a svn checkout of the GOMP/OpenMP source
dir
155860
svn://gcc.gnu.org/svn/gcc/trunk
svn://gcc.gnu.org/svn/gcc
and build/installed recent versions of gmp, mpfr, mpc:
gmp-4.3.2 mpc-0.8.1 mpfr-2.4.2
in /usr/local
I configured gcc with
$ ./configure --with-gmp=/usr/local --with-mpfr=/usr/local
--with-mpc=/usr/local
My current gcc is
Using built-in specs.
Target: x86_64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--enable-checking=release --with-system-zlib --enable-__cxa_atexit
--disable-libunwind-exceptions --enable-libgcj-multifile
--enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk
--disable-dssi --enable-plugin
--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic
--host=x86_64-redhat-linux
Thread model: posix
gcc version 4.1.2 20080704 (Red Hat 4.1.2-44)
I also did:
export LD_LIBRARY_PATH=/usr/local/lib
export LIBRARY_PATH=/usr/local/lib
I then started building gcc and it failed after a while:

However, 'make check' when I built libgmp worked, so I believe the
libgmp.so is valid. checking the installed version shows:
# ldd /usr/local/lib/libgmp.so
libc.so.6 => /lib64/libc.so.6 (0x00002b8f69b5d000)
/lib64/ld-linux-x86-64.so.2 (0x0000003a05c00000)

So I'm not sure why this gcc build step failed, unable to read symbols.
