GNU Smalltalk, part deux

Here's the current scoop. If there is a place to find more information, please let me know.

• builds successfully on FreeBSD/x86 5.0rc1, but fails sigsegv stack overflow test
• builds, tests, and installs successfully on Linux/x86 (Slackware 8.1, fresh install)
• still not building on Linux/PPC (invalid character '^?' makes CFuncs.st barf)
• uses libiberty.h, which Mac OS X.1 doesn't seem to include (and I'm too lazy to do a binutils install on it)

I'm thinking it's an issue with big-endian machines -- can anyone with a big-endian machine take a few minutes to build 2.0k and see if it works? If it's a generic issue with big-endian machines I think I can find it, but if not, I've still got a bit more digging to do.
