This one is harmeless: libunwind does an autoconf test to see if
-static-libcxa is accepted by the compiler without an error.  If so,
it will use that option, since it is needed when building with the
Intel compiler.  Unfortunately, the autoconf test doesn't check for
warnings.  If anybody knows how to test for "accepted with no error
and no warning", please let me know.

It appears to build fine on the machine I have access to
(spe189.testdrive.hp.com).  It seems to run RHEL AS3, with binutils
2.14.90.0.4.

Having said that, the x86-64 support is certainly work-in-progress.
