I've attached the required logs. Essentially the problem seems to

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.
Can you send the config.log file generated by configure? What else
is in the xlc_r_64 shell script, other than the -q64 option?
I've attached the config.log, and here's what all of the *_64 scripts
look like.
Can you try compiling without the -qkeyword=__volatile__? It looks
like XLC now has some support for GCC-style inline assembly, but it
doesn't seem to be working in this case. If that doesn't work, try
setting CFLAGS and CXXFLAGS to include -qnokeyword=asm, which should
disable GCC inline assembly entirely. I don't have access to a linux
cluster with the XL compilers, so I can't verify this. But it should
work.
