Hi, today I tried to build openmpi-v1.8.5-40-g7b9e672 on my machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-4.9.2 and Sun C 5.13 and I got the same error on all three platforms with both compilers.

Thank you very much for any help in advance. Kind regards Siegmar
