From: "Billy G. Allie" <Bill.Allie@mug.org>

The following patches will allow postgreSQL 6.3 to compile and run on a
UNIXWARE 2.1.2 system with the native C compiler with the following library
change:

        The alloca function must be copied from the libucb.a archive and added
        to the libgen.a archive.

Also, the GNU flex program is needed to successfully build postgreSQL.
