I have not heard from you since I queried if you wanted a complete copy of
by GCC source tree.

I have had not problems building every version of GCC since 2.6.3

Ok for some versions the riscbsd patches may need tweeking but this is only to
be expected until the riscbsd patches are merged into the GCC source tree.

I have never had any serious problems and I would have though that if you are
about to undertake a project like this you would be able to hack the few
potential problem areas with the patches.

The only real patch is the config .h file for riscbsd the rest is just fixing
the configuration scripts to recognise the host and target and this is trivial
for someone hacking at GCC.

A fast maths library does not *require* cross compiling so what is wrong with
the gcc in the netbsd tree ? This compiles under RiscBSD with the following
commands

tar xfz gnu.tar.gz
cd src/gnu/usr.bin/gcc
make

I cannot help unless I know exactly what problems you have with the compile and
I thought after my last message that you had things compiling.
