[PATCH 0/5] Update compat/regex

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

Here's a (hopefully) final version of this series. Changes since the
v2 RFC:

 * Re-apply Frank Li's regerror() patch already in Git as
   v1.6.5-rc2~23. There was no need to apply another msvc fix,
   v1.7.0-rc0~15, because it had already been fixed upstream.

 * Include Jonathan Nieder's autoconf patch and add his Acked-by to
   the rest, add my Tested-by to his.

 * Fix text alignment in one of the commit messages.

Note: This patch is intentionally diff --check unclean so we don't
diverge from upstream. This series can also be pulled from
http://github.com/avar/git/tree/update-fallback-regex-engine-v3 if the
whitespace causes issues with git-am.

Frank Li (1):
  Change regerror() declaration from K&R style to ANSI C (C89)

Jonathan Nieder (1):
  autoconf: don't use platform regex if it lacks REG_STARTEND

Ævar Arnfjörð Bjarmason (3):
  compat/regex: use the regex engine from gawk for compat
  compat/regex: get the gawk regex engine to compile within git
  t/t7008-grep-binary.sh: un-TODO a test that needs REG_STARTEND
