[PATCH 0/3] maintainer cleanups

I'm hoping to make a release before the year is out; I'm pushing
these cleanup patches, before starting my tests on several systems.

Eric Blake (3):
  build: update to latest gnulib
  maint: move syntax check exemptions into cfg.mk
  maint: enable tight_scope syntax check
