Skip one of the tests in flush2.c since it looks like VMS system
flsuhes the file anyway (like on Winodws with DLLs)
Renamed files family*.h5 that are used in backward compatibility
testing to have only one '.' in a file name, otherwise VMS system
becomes confused and test fails.
Cleaned up the only test (Fortran multi-file test) that is failing on
VMS (C counterpart passesa).
Added new script to facilitate the build process on VMS
Updated MANIFEST
PLatforms tested: VMS server, kagiso and linew (minor changes)
