Okay - so re-running everything via gcc -c file.c - here are the file
contents and the error output (scripted the run for uniformity):

FWIW - guile 1.8.3 does compile, and passes all of 'make check' on
Ubuntu 7.10 (gutsy) using gcc version 4.1.3 20070929 (prerelease)
(Ubuntu 4.1.2-16ubuntu2).  

However, all of the code snippets listed above fail in exactly the same
way on Ubuntu as they did on AIX.  So I'm guessing that some config
guessing is wrong on AIX, and either it's trying to compile code
segments that isn't being compiled on Linux, or it's not including
something that is being included on Linux to stop the errors.

I'm diffing the config.h's now and will experiment a bit with changes to
see if I can find the magic "wtf" particle.
