Well actually i wanted to use my own gmp. That is way i added them to the 
source, see http://gcc.gnu.org/install/prerequisites.html:

  "Alternatively, if a GMP source distribution is found in a subdirectory 
  of your GCC sources named gmp, it will be built together with GCC. "

This used to work under darwin 10.5 (Leopard) but does not seem to
work any more under 10.6 (Snow Leopard). BTW i tried this to

 --with-gmp=.../bla/local-build-tree

but no succes either.  If i don't supply them it fails because my 
onboard GMP is too low a version:

   configure: error: Cannot find GMP version 4.1.3 or higher.

The one of Chris don't. That is also strange. 

I asked the mprf boys, they did not understood it 
  http://news.gmane.org/gmane.comp.lib.mpfr.general
(btw link will expire in a few days)

Asked the gcc cross-compiling newsgroup too, no luck there.

I think gcc took a bad turn making it depend on all those
libs  (gmp,mpfr,mpc,ppl,cloog) of which you never have the 
correct version for your system. (and which have version 
dependencies among each other too) It seems they forgot us 
cross compilers out there.
