I can confirm this appears to be fixed in the "1.5a1r4236M" tarball
which Jeff provided off-list.

Thanks, this should be fixed in trunk>= r4230, I'll backport in other
branches soon. We didn't need add -lm for fabs() because gcc uses an
intrinsics, and libxml2 depends on libm, quite lucky.

The problem I described below is ALSO present in hwloc-1.4

When Jeff Squyres indicated that ompi-1.5.5 will use hwloc-1.3.x, I

I am sorry I didn't find this in the 1.3.1rc2, but when it came out
Dec 15 I wasn't setup as well for testing as I am now.
What I have found is that with the Solaris Studio 12.2 and 12.3
compilers I see link failures in util/ from "make all".
This has been seen on both Solaris/x86-64 and Linux/x86-64, but
Solaris/SPARC seems to be OK.
Here is what I see with "make V=1" on Solaris:

The problem in both cases appears to be that libhwloc.so needs libm
for fabsf(), but the library dependency is not resolved.
Though the Solaris build above was configured w/ CFLAGS=-m32, setting
CFLAGS=-m64 fails in the same way.
I *can* build hwloc-1.3.1 w/ gcc on the hosts where the SS12.x
compilers fail.
