Obsolete Options and/or Features
================================

   This section describes features and/or command line options from the
previous release of `gawk' that are either not available in the current
version, or that are still supported but deprecated (meaning that they
will *not* be in the next release).

   For version 2.15 of `gawk', the following command line options from
version 2.11.1 are no longer recognized.

`-c'
     Use `-W compat' instead.

`-V'
     Use `-W version' instead.

`-C'
     Use `-W copyright' instead.

`-a'
`-e'
     These options produce an "unrecognized option" error message but
     have no effect on the execution of `gawk'.  The POSIX standard now
     specifies traditional `awk' regular expressions for the `awk'
     utility.

   The public-domain version of `strftime' that is distributed with
`gawk' changed for the 2.14 release.  The `%V' conversion specifier
that used to generate the date in VMS format was changed to `%v'.  This
is because the POSIX standard for the `date' utility now specifies a
`%V' conversion specifier.  *Note Functions for Dealing with Time
Stamps: Time Functions, for details.
