Change regerror() declaration from K&R style to ANSI C (C89)

lznuaa · gitster · commit de831726decd · 2010-08-18T14:06:54.000-07:00
The MSVC headers typedef errcode as int, and thus confused the compiler in
the K&amp;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.
