compiling gcc 4.4.1 on Darwin 10.4 x86
Darwin -- not MacOSX
same error with and without -disable-bootstrap
perhaps I should remove -O2 for the first go around?
I'll try that.
Nope, same error.

hm..mayybe I should just change it to:
level2->assoc = 0;
Maybe this is because the configuration is detected as plain old i386?
For now I've removed a bunch of the code and removed -Wall.
(memset(0) the various structs)
I'll try again later with an explicit higher architecture.
Building Apple's gcc I was getting an illegal instruction..seemingly in libc.dylib but I didn't conform.
I tried changing Apple's code to use i586 instead of i686. No luck.
So I'm trying the FSF release and its build process (Apple has some custom scripts that I was using with their tree).
Then it gets further..darnit..:
checking how to run the C preprocessor... /lib/cpp
configure: error: in `/obj/i386-apple-darwin8.0.1/x86_64/libgcc':
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
