Dropping -mieee-fp from csiro.cmake fixes it for me.
Hi Orion:
For i686 hardware and your patched case, what is the result of the test?
In other words, does the CMake output say
"Check for NaN awareness in C compiler - found"
or
"Check for NaN awareness in C compiler - not found"
followed by
WARNING: Setting PL_HAVE_QHULL and WITH_CSA to OFF.
?
The latter result is a fairly serious constraint on our plgrid
function for i686 hardware. So I am hoping for the former result
since that simply means the gcc option -mieee-fp is no longer required
to get this NaN test to work correctly on i686 hardware.

Sorry I wasn't clear. The test was failing because of the compile
error. With the patch the test returns "found" and the build is
normal/successful.
