This is a copy since Gawk doesn’t use Gnulib. * lib/di-set.h (_GL_ATTRIBUTE_NONNULL): Remove definition that is incompatible with gl_COMMON_BODY’s. All uses changed. * lib/fts.c: Include attribte.h, for FALLTHROUGH. Keep the existing FALLTHROUGH definition since Glibc might use it, and it does no harm to Gnulib’s FALLTHROUGH. * lib/fts_.h, lib/inttostr.h: (__GNUC_PREREQ): Remove; no longer needed. (__attribute_warn_unused_result__): Remove. All uses replaced by _GL_ATTRIBUTE_NODISCARD. * lib/gl_list.h, lib/gl_map.h, lib/gl_omap.h, lib/gl_oset.h: * lib/gl_set.h: Prefer _GL_ATTRIBUTE_NODISCARD to an ifdeffed __attribute__ ((__warn_unused_result__)), for forward compatibility to C2X. * lib/hash.h (_GL_ATTRIBUTE_WUR): Remove. All uses replaced by _GL_ATTRIBUTE_NODISCARD. (_GL_ATTRIBUTE_DEPRECATED): Remove, since gl_COMMON_BODY defines it. * lib/ino-map.h (_GL_ATTRIBUTE_NONNULL): Remove. All uses replaced by gl_COMMON_BODY’s implementation, which has a slightly different signature. * lib/safe-alloc.h (_GL_ATTRIBUTE_RETURN_CHECK): Remove. All uses replaced by _GL_ATTRIBUTE_NODISCARD. * lib/unused-parameter.h (_GL_UNUSED_PARAMETER): Define in terms of _GL_ATTRIBUTE_MAYBE_UNUSED. No doubt all uses should be replaced, at some point. * m4/gnulib-common.m4 (_GL_GNUC_PREREQ): New macro. (_Noreturn): Use it. (_GL_HAS_ATTRIBUTE, _GL_ATTRIBUTE_ALLOC_SIZE) (_GL_ATTRIBUTE_ALWAYS_INLINE, _GL_ATTRIBUTE_ARTIFICIAL) (_GL_ATTRIBUTE_COLD) (_GL_ATTRIBUTE_DEPRECATED, _GL_ATTRIBUTE_ERROR) (_GL_ATTRIBUTE_WARNING, _GL_ATTRIBUTE_EXTERNALLY_VISIBLE) (_GL_ATTRIBUTE_FALLTHROUGH, _GL_ATTRIBUTE_FORMAT) (_GL_ATTRIBUTE_LEAF, _GL_ATTRIBUTE_MAY_ALIAS) (_GL_ATTRIBUTE_MAYBE_UNUSED) (_GL_ATTRIBUTE_NODISCARD, _GL_ATTRIBUTE_NOINLINE) (_GL_ATTRIBUTE_NONNULL, _GL_ATTRIBUTE_NONSTRING) (_GL_ATTRIBUTE_NOTHROW, _GL_ATTRIBUTE_PACKED, _GL_ATTRIBUTE_PURE) (_GL_ATTRIBUTE_SENTINEL): New macros. * modules/backup-rename, modules/backupfile, modules/c-vasnprintf: * modules/fnmatch, modules/freopen-safer, modules/fts: * modules/mbrtoc32, modules/mbrtowc, modules/nstrftime: * modules/quotearg, modules/savewd: * modules/unistdio/u16-u16-vasnprintf: * modules/unistdio/u16-vasnprintf: * modules/unistdio/u32-u32-vasnprintf: * modules/unistdio/u32-vasnprintf: * modules/unistdio/u8-u8-vasnprintf: * modules/unistdio/u8-vasnprintf: * modules/unistdio/ulc-vasnprintf: * modules/unistr/u8-uctomb, modules/vasnprintf: (Depends-on:): Add attribute module.
