[svn-r21063] Description:
    Tweak make_vers script so that it indents preprocessor commands inside
#ifdefs, is more forgiving and informative about the input file's prefix, and
is better parameterized with the global variables at the beginning of the
script.  When major versions are branched from the trunk, the $max_idx value
should be the only value that needs to be changed in the version of the script
on the trunk.

    Changes to H5version.h file are just indention.

Tested on:
    Mac OS X/32 10.6.8 (amazon)
    (too minor to require h5committest)
