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.
