When you configure the gcc 2.3.1 for sco version 3.2v4, e.g. with the call:

	configure --target=i386-*-sco3.2v4*

the sub-script 'config.sub' returns "i386-unknown-sco3.2v2" (instead of ...v4)
and configure is unable to differ between the older version "...3.2v2" and
the newer one "...3.2v4" - allthough the 'configure' script would like to
treat these versions differently.

Presumably 'config.sub' should be expanded like this:


	--- 1.1	1992/12/11 09:38:53
