Compiling 1.9.1p0 on AIX 5.3 using xlc

Hi,

I'm trying to compile Ruby using the native compiler xlc on AIX.  Ruby
seems to have compiled, but it falls over with a SEGV as soon as I run
'make test', it falls over.

The reason I want to use the native compilers rather than gcc is to be
sure that C++ name mangling is not an issue when I link Ruby's libraries
with my own code.

The output and my rbconfig.rb are attached below.  Anyone have any
ideas?

Cheers,
Graza.
