I believe the problem is likely to only be seen on the T2+ or similar
processors. Someone noticed the library code in OpenSolaris is different on the
T2+ processor to what it would be on a more common SPARC processor. 

I have built gcc 4.4.0 on Solaris 10 on a Sun Blade 2000 (UltraSPARC II
processors) and have no problem with mpfr, but on the T2+ processors of the
T5240 server, it does not work.  

I'll try a later snapshot, but any serious gcc developer would be welcome to an
account on the machine where it fails. That does not mean anyone that just
happens to be interested and fancies playing on a 16-core machine, but if you
are a serious gcc developer, then I could give you an account.
