(GUILE_PROGS, GUILE_SITE_DIR, GUILE_CHECK,
GUILE_MODULE_EXPORTS, GUILE_MODULE_REQUIRED_EXPORTS): New macros. (GUILE_MODULE_CHECK): Renamed from AC_GUILE_MODULE_CHECK. Rewritten to expect `description' as a present-tense verb phrase. (GUILE_MODULE_AVAILABLE, GUILE_MODULE_REQUIRED): Renamed likewise.
