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.
