Subject: Re: [OMPI devel] OpenMPI 1.4.2 and PathScale 3.2 C++

Among the tests I conducted but did not report was a successful build of
1.5rc5 with the PathScale "3.2.99" compilers.
$ pathcc --version
PathScale(TM) Compiler Suite: Version 3.2.99
Built on: 2009-08-21 13:23:57 -0500
Thread model: posix
GNU gcc version 4.2.0 (PathScale 3.2.99 driver)

This was a beta release of the 3.3 (never released?) provided to some
customers, and not a general release.

I also note that my PathScale install is using gcc-4, rather than gcc-3,
which I understand contains different bugs.

I will test the "stock" 3.2 with 1.5rc5 and 1.4.3rc1 and report my findings.
