Hi Mark,
Here's the info on the two systems - first the SPARC system, secondly the Intel
Xeon system.
1) SPARC
* Sun Blade 2000, with 2 x UltraSPARC III+ 1200 MHZ processors
* 8 GB RAM
* Solaris 10 update 8 10/09 release (This is the latest release of Solaris 10).
drkir...@swan:~$ cat /etc/release

drkir...@swan:~$ uname -a
SunOS swan 5.10 Generic_141444-09 sun4u sparc SUNW,Sun-Blade-1000
Python 2.6.4 (r264:75706, Jun 24 2010, 10:39:29)

>>> float.fromhex('-0x0.0p+0')

When configure runs, I see:
"checking for copysign... yes"
In pyconfig.h I have:
/* Define to 1 if you have the `copysign' function. */
#define HAVE_COPYSIGN 1

2) Intel Xeon system.
* Sun Ultra 27, quad core 3.33 GHz Intel Xeon processor
* 12 GB RAM
* OpenSolaris 06/2009, updated to build 134
* 64-bit installation.
* Note, this is the native operating system on this machine, so VirtualBox is
not used.

If you feel access to the SPARC system could help you debug this (or any of the
other test failures I get), I can get you access to a machine 16-core Sun T5240
which was donated by Sun.
I can't provide such easy access to the Xeon system, though you can install
OpenSolaris as a Virtual machine in VirtualBox quite easily - its a free
download.
