| Subject: | [PATCH] assorted File::Spec::VMS fix-ups |
- Make catpath return an empty directory rather than the current
directory if the directory name is empty. This allows catpath
to play nice with non-rooted logical names, as in
catpath('sys$login:', '', 'login.com');
- Fix abs2rel bug in handling a Unix-style input.
- Assorted clarification and simplification of the documentation.

-The mode of operation of these routines depend on the VMS features that
-are controlled by the DECC features C<DECC$FILENAME_REPORT_UNIX> and
-C<DECC$EFS_CHARSET>.
+The default behavior is to allow either VMS or Unix syntax on input and to
+return VMS syntax on output, even when Unix syntax was given on input.
-Perl needs to be at least at 5.10 for these feature settings to work.
-Use of them on older perl versions on VMS will result in unpredictable
-operations.
-
-The default and traditional mode of these routines have been to expect VMS
-syntax on input and to return VMS syntax on output, even when Unix syntax was
-given on input.
-
-The default and traditional mode is also incompatible with the VMS
-C<EFS>, Extended File system character set, and with running Perl scripts
-under <GNV>, Gnu is not VMS, an optional Unix like runtime environment on VMS.
-
-If the C<DECC$EFS_CHARSET> feature is enabled, These routines will now accept
-either VMS or UNIX syntax. If the input parameters are clearly VMS syntax,
-the return value will be in VMS syntax. If the input parameters are clearly
-in Unix syntax, the output will be in Unix syntax.
-
-This corresponds to the way that the VMS C library routines have always
-handled filenames, and what a programmer who has not specifically read this
-pod before would also expect.
-
-If the C<DECC$FILENAME_REPORT_UNIX> feature is enabled, then if the output
-syntax can not be determined from the input syntax, the output syntax will be
-UNIX. If the feature is not enabled, VMS output will be the default.
+When used with a Perl of version 5.10 or greater and a CRTL possessing the
+relevant capabilities, override behavior depends on the CRTL features
+C<DECC$FILENAME_UNIX_REPORT> and C<DECC$EFS_CHARSET>. When the
+C<DECC$EFS_CHARSET> feature is enabled and the input parameters are clearly
+in Unix syntax, the output will be in Unix syntax. If
+C<DECC$FILENAME_UNIX_REPORT> is enabled and the output syntax cannot be
+determined from the input syntax, the output will be in Unix syntax.
