I've attached the required logs. Essentially the problem seems to
be that the XL Compilers fail to recognize "__asm__ __volatile__" in
opal/include/sys/powerpc/atomic.h when building 64-bit.

I've tried using various xlc wrappers such as gxlc and xlc_r to
no avail. The current log uses xlc_r_64 which is just a one line
shell script forcing the -q64 option.

The same works flawlessly with gcc-4.1.0. I'm using the nightly
build in order to link with Torque's new shared libraries.

Any help would be greatly appreciated. For reference here are
a few other things that may provide more information.
