How are you building gcc-3.3.2?  I recommend
http://www.kegel.com/crosstool/crosstool-0.28-rc37.tar.gz ...

The following patch is supposed to fix problems related to
printf("%f", 1.0) on arm, I think:
http://www.kegel.com/crosstool/crosstool-0.28-rc37/patches/glibc-2.3.2/glibc-fp-byteorder.patch

You may also want the riskier patch
http://www.kegel.com/crosstool/crosstool-0.28-rc37/patches/gcc-3.3.2/feature/gcc-3.3.2-arm-softfloat.patch
but I can't promise that one's quite right for all users.

Let us know how it goes.
