C++: icc 7 and MPICH-GM-1.2.5..10 not working!?

hi everybody,

i just noticed that (for our system) there is no C++ support for the
combination Intel C++ compiler version 7 and MPICH-GM 1.2.5..10.

using "mpich.make.intel_ia32" for our SuSE SLES8 linux systems, C++
support seems to be switched off by "configure":

---------------------------------------------------------------------
Compiling C++ interface with icc
checking whether filesystem respects case in file names... yes
checking for current directory name... /usr/local/src/Myri/mpich-1.2.5..10
checking for architecture... LINUX
checking for install
checking for ranlib
checking gnumake... yes using --no-print-directory
checking whether make supports include... yes
checking OSF V3 make... no
checking for virtual path format... VPATH
checking if icc returns correct error code... yes
checking that selected C++ compiler can compile iostream.h... no!...Cannot
use icc compiler
-----------------------------------------------------------------------

is that a known problem? any ideas or workarounds?

thanks four your support,

  christian
