Thanks Ralf!
Dresden/VT guys: can you apply the VT-related patches, and look into
the AX_OPENMP issue? I'll apply the ptmalloc2 patch.

Hello,
I tried to build OpenMPI trunk on my Debian stable/testing mix,
and to make things more interesting, today my /bin/sh is dash,
and while gcc is version 4.3.1, g++ remained at 4.1.3.
I needed the following patch in order to get configure to finish
("test ... == ..." is a bash extension).
Then, the build failed with:

This is because GCC 4.1.3 doesn't know about -fopenmp. The
AX_OPENMP is
called in ACVT_OMP (in ompi/contrib/vt/vt/acinclude.m4) only for the C
compiler, not the C++ one. Note that the AX_OPENMP is suited to be
called for multiple languages (e.g., wrapped in AC_LANG_PUSH(...) ...
AC_LANG_POP(...)). However, OpenMPI may decide to not allow for
different compiler settings here, or at least require that all
compilers
used do OpenMP. As I don't know what's desirable, no proposed patch
here.
Cheers,
Ralf
