[PATCH 0/7] maintenance patches

[Eric Blake]

I'm trying to get ready for a maintenance release of m4, to
address several complaints of FTBFS with newer glibc; as
such, I'm pushing this series on branch-1.4, and hope to make
time to sync things to branch-1.6 and master.

Eric Blake (7):
  doc: fix misuse of @xref
  build: silence gcc warning
  build: mark several pure functions
  build: pick up latest gnulib fixes
  build: add more compiler checking
  maint: drop CVS cruft
  maint: merge gitignore files
