Rainer and I are still iterating on the trunk solution (we moved to an
hg branch just for convenience for the moment).
Note that the Fortran flags aren't too important to OMPI. We *only*
use them in configure. OMPI doesn't contain any Fortran 77 code at
all, and the F90 module is extremely minimalistic (generally one-line
subroutines to call the C counterpart). So a workaround for the
moment -- until we can figure out the problem -- might be to remove
the -fast from the FFLAGS and FCFLAGS.

Dear Michel,
per the naming convention test in configure:
ifort -fast
will turn on -xHOST -O3 -ipo -no-prec-div -static,
of which -ipo turns on interprocedural optimizations for multiple
files.
Here the compiled object file does not contain the symbols searched
for in the
configure-tests.
Looking into the simple test-case in configure and the options that
one has to
figure out the naming convention using compilation (-c), I don't see
an other
other than disabling -fast & -ipo for intel-fortan compilers.
Please check trunk in commit r21363.

In order to statically link at least the intel-libraries, please add
-static-intel (in previous intel compilers called -i-static)
to LDFLAGS
With best regards,
