Miguel, after a similar set of problems in the last few days, I
recommend taking the steps suggested by Andrew Haley:

Start with a freshly unzipped source directory:

  $ tar -xvjf gcc-4.5.1.tab.bz2

and download this file into it:

  http://gcc.gnu.org/svn/gcc/trunk/contrib/download_prerequisites

Then:

  $ cd gcc-4.5.1
  $ sh ./download_prerequisites

That will get the exact versions of gmp, mpfr, and mpc that are used
by the developers and you will have the best chance of getting all
their configurations correct.

Then make a build directory OUTSIDE the source tree.

  $ cd ..                 # it is STRONGLY recommended NOT to build in
the source tree
  $ mkdir objdir
  $ cd objdir
  $ ../gcc-4.5.1/configure ......
  make.....

I think you will have better luck.

HTH.
