I have tested builds of gmp/mpfr/mpc on : 1) x86_64-Linux2.6.18-274.17.1.el5 2) x86_64-Linux2.6.32-220.4.1.el6.x86_64 3) sparc-SunOS5.10 4) plus various others ( ppc970 et al ) seen no major problems thus far. Also, gmp,mpfr,mpc all build fine with all tests passed even on a very very old : titan-i386-SunOS5.8 $ uname -X System = SunOS Node = titan Release = 5.8 KernelID = Generic_127722-03 Machine = i86pc BusType = <unknown> Serial = <unknown> Users = <unknown> OEM# = 0 Origin# = 1 NumCPU = 2 titan-i386-SunOS5.8 $ psrinfo -v Status of virtual processor 0 as of: 03/12/12 11:47:00 on-line since 04/28/11 17:39:44.

HOWEVER, I do use the very latest revs of mpfr,gmp and mpc. dc -- -- http://pgp.mit.edu:11371/pks/lookup?op=vindex&search=0x1D936C72FA35B44B +-------------------------+-----------------------------------+ | Dennis Clarke | Solaris and Linux and Open Source | | dcla...@blastwave.org | Respect for open standards. | +-------------------------+-----------------------------------+
