Subject: [OMPI devel] openmpi-1.9a1r27710 on cygwin: patch and questions

Hi,
additional to the patches used for building on cygwin
openmpi-1.7rc5, a new one is needed for openmpi-1.9a1r27710 build.
See attached for statfs usage.

As config parameters, I added "if-windows,shmem-windows"
to
 
--enable-mca-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv,if-windows,shmem-windows

Question 1 :
instead of a platform check should be better to check
if statvfs or statfs are implemented on the platform ?

Question 2:
any specif reason to have reset the shared library
version numbers ?

On openmpi-1.9a1r27710
./usr/bin/cygmpi-0.dll
./usr/bin/cygmpi_cxx-0.dll
./usr/bin/cygmpi_mpifh-0.dll
./usr/bin/cygmpi_usempi-0.dll
./usr/bin/cygopen-pal-0.dll
./usr/bin/cygopen-rte-0.dll
./usr/lib/openmpi/cygompi_dbg_msgq.dll

On openmpi-1.7rc5
./usr/bin/cygmpi-1.dll
./usr/bin/cygmpi_cxx-1.dll
./usr/bin/cygmpi_mpifh-2.dll
./usr/bin/cygmpi_usempi-1.dll
./usr/bin/cygopen-pal-5.dll
./usr/bin/cygopen-rte-5.dll
./usr/lib/openmpi/cygompi_dbg_msgq.dll

Question 3:
  there is an alternative way to exclude all the "*-windows" mca
  instead of
--enable-mca-no-build=installdirs-windows,timer-windows,if-windows,shmem-windows

Regards
Marco
