+       argp: make HAVE_DECL usage consistent
+       * lib/argp-parse.c (__argp_parse): Check contents of HAVE_DECL
+       macros, not whether they are defined.
+       * m4/argp.m4 (gl_ARGP): Always define HAVE_DECL_* macros, per
+       convention with other declaration checks.
+       Reported by Karel Zak, with suggestions from Paul Eggert.
