assure: new module This works better than 'assert' when compiling with -DNDEBUG, as it avoids some compiler diagnostics in that case. Reported by Norihiro Tanaka in: http://lists.gnu.org/archive/html/bug-gnulib/2014-12/msg00215.html * MODULES.html.sh (func_all_modules): Add 'assure'. * lib/assure.h, modules/assure: New files. * lib/chdir-long.c, lib/cycle-check.c, lib/fchdir.c, lib/fts.c: * lib/poll.c, lib/savewd.c, lib/utimens.c, lib/xstrtol.c: Prefer 'assure' to 'assert'. * modules/chdir-long, modules/cycle-check, modules/fchdir: * modules/poll, modules/savewd, modules/utimens, modules/xstrtol: Depend on 'assure'.
