Subject:	OpenMPI installation bug: /usr/bin/mpif90 links to non-existent target
To:	Cygwin <cygwin AT cygwin DOT com>

I have the current versions of openmpi and libopenmpi installed in
Cygwin-64. The mpif90 command (MPI wrapper for Gfortran) does not
execute, even though /usr/bin/mpif90 exists. The problem is that
/usr/bin/mpif90 is a symbolic link to /usr/bin/mpifort.exe, which does
not exist. However /usr/bin/mpifort does exist (and is itself a link
to /usr/bin/opal_wrapper.exe). I have cured this by changing the
target of /usr/bin/mpif90:

$ ln -sf /usr/bin/mpifort /usr/bin/mpif90
