These include `find +-print0', `perl -0', `sort -z', and `xargs -0'. It'd be handy if GNU +grep also processed such file names. Here's a proposed patch to do +this, relative to grep 2.3c. This patch introduces two options, one +for the data, and one for the file names.

Poulson. + +1999-02-23 Paul Eggert + + Fix porting bug reported by Amakawa Shuhei for SunOS 4.1.4-JL. + The btowc.c shipped with grep 2.3 is incorrect for Solaris + 2.5.1 and earlier, as it assumes UTF8, which these OSes do not + support. Solaris 7 supports btowc, so there's no need to ship + a substitute for it. The only questionable case is Solaris + 2.6, which lacks btowc but does support UTF8. However, 2.6 + supports UTF8 but only as a demonstration (for an English + locale!); Japanese Solaris 2.6 users typically use EUC, or + sometimes shift-JIS, but they cannot use UTF8 since Japanese + UTF8 is not supported. Hence there's no point to having grep + substitute a btowc that uses UTF8, as it is either redundant, + or it will almost invariably have incorrect behavior. + + * configure.in (AC_CHECK_HEADERS): Don't set USE_WCHAR. + (AC_CHECK_FUNCS): Add btowc, wctype. + (AC_REPLACE_FUNCS): Don't replace btowc; our replacement is + invariably doing the wrong thing anyway, at least on SunOS/Solaris. + Don't bother to check for wctype in -lw, as we don't support + wide characters on Solaris 2.5.1 or earlier anyway. + + * bootstrap/Makefile.try (OBJS): Remove btowc.$(OBJEXT). + + * src/btowc.c: Removed; no longer needed. + +1999-02-19 Paul Eggert + + * NEWS: Fix typo when talking about the old behavior of + silently skipping directories; it was grep 2.1, not grep 2.2. + +1999-02-15 Alain Magloire + + * bootstrap/Makefile.try : add DJGPP DEFS. + Done by Elie Zaretsckii. + 1999-02-14 Alain Magloire * m4/gettext.m4 : Guard [] with changequote. |
