Update.
2002-11-30 Bruno Haible <bruno@clisp.org> * iconv/gconv.h (__gconv_btowc_fct): New typedef. (struct __gconv_step): New field __btowc_fct. * wcsmbs/btowc.c (__btowc): Use the __btowc_fct shortcut if possible. * iconv/gconv_int.h (__BUILTIN_TRANSFORM): Renamed from __BUILTIN_TRANS. (__gconv_btwoc_ascii): New declaration. * iconv/gconv_simple.c (BUILTIN_TRANSFORMATION): Add BtowcFct argument. (__gconv_btwoc_ascii): New function. * iconv/gconv_builtin.h: Add BtowcFct argument to all BUILTIN_TRANSFORMATION invocations. * iconv/gconv_conf.c (BUILTIN_TRANSFORMATION): Add BtowcFct argument. * iconv/iconvconfig.c (BUILTIN_TRANSFORMATION): Likewise. * iconv/gconv_builtin.c (map): New field btowc_fct. (BUILTIN_TRANSFORMATION): Add BtowcFct argument. Use it to initialize btowc_fct field. (__gconv_get_builtin_trans): Initialize __btowc_fct field. * iconv/gconv_cache.c (find_module): Initialize __btowc_fct field. * iconv/gconv_db.c (gen_steps, increment_counter): Likewise. * wcsmbs/wcsmbsload.c (to_wc, to_mb): Likewise. * iconv/skeleton.c: Document STORE_REST and FROM_ONEBYTE. (gconv_init): Initialize __btowc_fct field. Undefine EXTRA_LOOP_ARGS and FROM_ONEBYTE at the end. * iconv/loop.c: Document ONEBYTE_BODY. (gconv_btowc, FROM_ONEBYTE): Define if ONEBYTE_BODY is defined. Undefine ONEBYTE_BODY at the end. * iconvdata/8bit-generic.c (ONEBYTE_BODY): New macro. * iconvdata/8bit-gap.c (NONNUL): New macro. (BODY for FROM_LOOP): Use it. (ONEBYTE_BODY): New macro. * iconvdata/isiri-3342.c (HAS_HOLES): Set to 1. (NONNUL): New macro. * iconvdata/ansi_x3.110.c (ONEBYTE_BODY): New macro. * iconvdata/armscii-8.c (ONEBYTE_BODY): New macro. * iconvdata/cp1255.c (ONEBYTE_BODY): New macro. * iconvdata/cp1258.c (ONEBYTE_BODY): New macro. * iconvdata/tcvn5712-1.c (ONEBYTE_BODY): New macro. * iconvdata/big5.c (ONEBYTE_BODY): New macro. * iconvdata/big5hkscs.c (ONEBYTE_BODY): New macro. * iconvdata/euc-cn.c (ONEBYTE_BODY): New macro. * iconvdata/euc-jp.c (ONEBYTE_BODY): New macro. * iconvdata/euc-jisx0213.c (ONEBYTE_BODY): New macro. * iconvdata/euc-kr.c (ONEBYTE_BODY): New macro. * iconvdata/euc-tw.c (ONEBYTE_BODY): New macro. * iconvdata/gbk.c (ONEBYTE_BODY): New macro. * iconvdata/gb18030.c (ONEBYTE_BODY): New macro. * iconvdata/ibm932.c: Include <stdbool.h>. (TRUE, FALSE): Remove macros. (BODY for FROM_LOOP): Remove unused variable rp1. (ONEBYTE_BODY): New macro. (BODY for TO_LOOP): Use bool. * iconvdata/ibm932.h (__ibm932sb_to_ucs4_idx): Remove array. * iconvdata/ibm943.c: Include <stdbool.h>. (TRUE, FALSE): Remove macros.
