[bug-diffutils] [PATCH] Avoid gcc warning on Stratus OpenVOS building regex.c

[Green, Paul]

Gentle Diffutils Maintainers,

The Stratus OpenVOS port of gcc does not allow use of the regparm
attribute. The following patch to regex_internal.h eliminates a series
of warning messages when building lib/regex.c. This patch is against the
newly-released diffutils-3.1 files. With this patch in place, diffutils
builds without warnings or errors on OpenVOS Release 17.1.
