Quincey Koziol fd547cd11f [svn-r18413] Description:
Unify srcdir handling for test executables and allow them to use the srcdir
setting from configure time without requiring the 'srcdir' environment variable
be set (although you still can, to override the built in setting).  Attempted
to get this right for Windows builds also.

    Also add dependency between src/H5Tinit.c and src/libhdf5.settings, so
that the test/testcheck_version.sh script works correctly.

Tested on:
    Linux/32 2.6 (jam)
    Mac OS X/32 10.6.2 (amazon)
