Message : Implement the //NON_IDENTICAL_DISCARD suffix from POSIX:2024. * include/iconv.h.in (ICONV_GET_DISCARD_INVALID, ICONV_SET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL, ICONV_SET_DISCARD_NON_IDENTICAL): New macros. * lib/converters.h (struct conv_struct): Change type of discard_ilseq to 'unsigned int'. (DISCARD_INVALID, DISCARD_UNCONVERTIBLE): New macros. * lib/iconv.c (iconv_open, iconv_open_into): Change type of discard_ilseq to 'unsigned int'. (iconvctl): Implement ICONV_GET_DISCARD_INVALID, ICONV_SET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL, ICONV_SET_DISCARD_NON_IDENTICAL. Change the implementation of ICONV_GET_DISCARD_ILSEQ, ICONV_SET_DISCARD_ILSEQ to test/set both bits. * lib/iconv_open1.h: Update comment. Recognize //NON_IDENTICAL_DISCARD. * lib/iconv_open2.h: Update comment. * lib/loop_unicode.h (mb_to_uc_write_replacement): Test the DISCARD_UNCONVERTIBLE bit of discard_ilseq. (unicode_loop_convert): Test the respective bit of discard_ilseq. (unicode_loop_reset): Test the DISCARD_UNCONVERTIBLE bit of discard_ilseq. * lib/loop_wchar.h (wchar_from_loop_convert, wchar_to_loop_convert): Test the DISCARD_INVALID bit of discard_ilseq. * man/iconv_open.3: Mention the //NON_IDENTICAL_DISCARD suffix. Mark as conforming to POSIX:2024. * man/iconv.3: Likewise. * man/iconv_close.3: Mark as conforming to POSIX:2024. * man/iconv.1: Likewise. * man/iconvctl.3: Document ICONV_GET_DISCARD_INVALID, ICONV_SET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL, ICONV_SET_DISCARD_NON_IDENTICAL. Revise the description of ICONV_GET_DISCARD_ILSEQ, ICONV_SET_DISCARD_ILSEQ. * tests/test-discard.c (test_default, test_translit, test_ignore, test_ignore_translit): Test also the ICONV_GET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL accessors. (test_nid, test_nid_translit, test_invd, test_invd_translit): New functions. (main): Add test cases with //NON_IDENTICAL_DISCARD suffix. * NEWS: Mention the change.
