Hi Corinna,
is something changed in the file open interface ?

On latest snaphots, but not on 1.7.5-1, I got unexpected
results on hdf5-1.8.5 build checks, when testing 
if a file is already there.

Testing  -- Low-Level File I/O (file)
*** UNEXPECTED VALUE from H5Fcreate should be -1, but is 16777217 at line  149 in /pub/cygports/hdf5/hdf5-1.8.5-1/src/hdf5-1.8.5/test/tfile.c
*** UNEXPECTED VALUE from H5Fclose should be -1, but is 0 at line  158 in /pub/cygports/hdf5/hdf5-1.8.5-1/src/hdf5-1.8.5/test/tfile.c

Of course it is possible that hdf5 is wrongly assuming
something and it is not a snapshot fault.
