No longer needed, since we assume + C89 or better. All uses removed. + +2005-08-19 Paul Eggert + + * regex_internal.c (re_acquire_state, re_acquire_state_context) + [defined lint]: Suppress bogus uninitialized-variable warnings. + + * regcomp.c (duplicate_node): Return new index, not an error code, + and let the caller return REG_ESPACE if out of space. This + removes an uninitialied-variable warning with GCC 4.0.1, and also + avoids taking the address of a local variable. All callers + changed. + +2005-08-19 Jim Meyering + + * regexec.c (proceed_next_node): Redo local variables to + avoid GCC shadowing warnings. + +2005-08-19 Paul Eggert + + * regex_internal.c (re_string_realloc_buffers, re_node_set_insert): + (re_node_set_insert_last, re_dfa_add_node): + Rename local variables to avoid GCC shadowing warnings. + +2005-08-18 Bruno Haible + + * strstr.c (strstr): Fix return value in multibyte case. + * strcasestr.c (strcasestr): Likewise. + +2005-08-17 Jim Meyering + + Make the %s format (seconds since the epoch) work for a negative + number and when used with a zero-padded field width, e.g. %015s. + + * strftime.c (my_strftime): Move the `do_number_sign_and_padding' + label so that it precedes the code to set `digits'. Otherwise, + %0Ns wouldn't work. Before this change, `date -d @-22 +%05s' would + print `00-22'. Now, it prints `-0022', as it should. + +2005-08-17 Paul Eggert + + * regex.h: Remove useless space-before-tab. From coreutils. + 2005-08-17 Bruno Haible * strcasestr.h: New file.
