I had the impression that the scope of using autotools is
to check for features not platforms.
*** OSHMEM Configuration options
checking if want oshmem... yes
configure: WARNING: OpenSHMEM support was requested, but currently
configure: WARNING: only supports Linux.
configure: error: Cannot continue
*** ERROR: configure failed
last time, some time ago, I built 1.9.x with oshmem this statement,
configure error, was not present.
Which feature is really needed ?
