What Dan should have said was that it would not fail on VMS because on VMS
ODS-2 volumes UPPERCASE is used to store filenames and they are
case-insensitive, so "README", "readme", "ReadMe" (and lots of other
variants) will all open the same file.

VMS ODS-5 volumes are CASE_PRESERVITIVE, but not CASE_SENSITIVE.  On VMS,
it's the user's (process) decision as to whether or not files are treated in
a case sensitive manner.
