Glad to have helped. Answering your question drew me to the same
evaluation and results.
Now the real work begins. ;)

It appears that my issue #1 is related to the default build of
gmp-4.2.2. On my iMac with its Core2 Duo chip, gmp's ./configure
script builds gmp with -m64 -mtune=k8. This appears to be the root
of the problems. The build should be 32-bit, not 64-bit, and my
machine does not have an AMD K8 in it!
Starting with gmp-4.2.2, I found success by doing:
./configure ABI="32" CFLAGS="-O2"
make -j4
sudo make install
Then with mpfr-2.3.1, I found success by doing exactly the same:
./configure ABI="32" CFLAGS="-O2"
make -j4
sudo make install
Then with the folder gcc-4.3-20080710 (the latest GCC snapshot), I
did:
cd gcc-4.3-20080710
mkdir build
cd build
../configure
make
and voila: gcc-4.3.1 builds!
Perhaps this info can be added to GCC release notes so that others
which want to build GCC-4.3 can build these required libraries
properly.
<soapbox>
It would be MUCH BETTER to make these libraries part of the GCC
sources as part of gcclib perhaps, and have them subsumed into a
coherent whole so that everyone does not have to deal with this.
GCC has way too many external dependencies. These dependencies
need to be removed!
</soapbox>
BTW, I discovered all of this because on FreeBSD-7.0 CURRENT I can
build gcc-4.3.1 and these libraries just fine on a Core2 Duo
Toshiba laptop of mine. I inspected their builds and found that
they were not 64-bit builds. That is what gave me the clue.
So the bug is that the ./configure of gmp works on FreeBSD but does
not on Mac OS X.
