BUG #2719: configure script does not accept --enable-locale --enable-multibyte=UNICODE options

The following bug has been logged online:

Bug reference:      2719
Logged by:          Mareks Malnacs

PostgreSQL version: 8.2 beta 2
Operating system:   macos x and solaris x86
Description:        configure script does not accept --enable-locale
--enable-multibyte=UNICODE options
Details:

I've downloaded 8.2 beta 2 from
http://www.postgresql.org/ftp/source/v8.2beta2/   (from 24.10.2006) and now
configure script forbids me to use following options:

--enable-locale --enable-multibyte=UNICODE --enable-odbc --with-java
--enable-unicode-conversion

From which w/o --enable-multibyte I can't use unicode (utf8) while creating
new database installation:

initdb -E UNICODE -A password -W

This command says that it will use C encoding instead of specified UNICODE,
which later on results in not usable database with a lot of localized
strings.
