[PATCH 3/5] Change regerror() declaration from K&R style to ANSI C (C89)

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

From: Frank Li <lznuaa@gmail.com>

The MSVC headers typedef errcode as int, and thus confused the compiler in
the K&R style definition. ANSI style deconfuses it.

This patch was originally applied as v1.6.5-rc2~23 but needs to be
re-applied since compat/regex was overwritten by Ævar Arnfjörð
Bjarmason with the gawk regex engine.
