> g++ cannot compile regex, possibly because of K&R style:
I installed the following patch into gnulib in an attempt to fix this,
and also submitted the corresponding bug reports to glibc.
Please let me know how it works for you.
(I still have more regex things to catch up on, but one step at a time....)
2005-08-20 Paul Eggert <address@hidden>
* config/srclist.txt: Add glibc bugs 1220, 1221, 1222.
* lib/regcomp.c:
(re_compile_pattern, re_set_syntax, re_compile_fastmap):
(re_compile_fastmap_iter, regcomp, regerror, regfree):
(re_compile_internal, init_dfa, init_word_char, free_workarea_compile):
(create_initial_state, optimize_utf8, analyze, postorder, preorder):
(optimize_subexps, lower_subexps, lower_subexp, calc_first, calc_next):
(link_nfa_nodes, duplicate_node_closure, search_duplicated_node):
(duplicate_node, calc_inveclosure, calc_eclosure, calc_eclosure_iter):
(fetch_token, peek_token, peek_token_bracket, parse, parse_reg_exp):
(parse_branch, parse_expression, parse_sub_exp, parse_dup_op):
(build_range_exp, build_collating_symbol, parse_bracket_exp):
(parse_bracket_element, parse_bracket_symbol, build_equiv_class):
(build_charclass, build_charclass_op, fetch_number, create_tree):
(create_token_tree, mark_opt_subexp, duplicate_tree):
Use prototypes rather than old-style definitions.
* lib/regex_internal.c:
(re_string_allocate, re_string_construct, re_string_realloc_buffers):
(re_string_construct_common, build_wcs_buffer, build_wcs_upper_buffer):
(re_string_skip_chars, build_upper_buffer, re_string_translate_buffer):
(re_string_reconstruct, re_string_peek_byte_case):
(re_string_fetch_byte_case, re_string_destruct, re_string_context_at):
(re_node_set_alloc, re_node_set_init_1, re_node_set_init_2):

(re_node_set_remove_at, re_dfa_add_node, calc_state_hash):
(re_acquire_state, re_acquire_state_context, register_state):
(create_ci_newstate, create_cd_newstate, free_state):
Likewise.
* lib/regexec.c (regexec, re_match, re_search, re_match_2, re_search_2):
(re_search_2_stub, re_search_stub, re_copy_regs, re_set_registers):
(re_search_internal, prune_impossible_nodes):
(acquire_init_state_context, check_matching, static):
(check_halt_node_context, check_halt_state_context, proceed_next_node):
(push_fail_stack, pop_fail_stack, set_regs, free_fail_stack_return):
(update_regs, sift_states_backward, build_sifted_states):
(clean_state_log_if_needed, merge_state_array):
(update_cur_sifted_state, add_epsilon_src_nodes):
(sub_epsilon_src_nodes, check_dst_limits, check_dst_limits_calc_pos_1):
(check_dst_limits_calc_pos, check_subexp_limits, sift_states_bkref):
(sift_states_iter_mb, transit_state, merge_state_with_log, static):
(find_recover_state, check_subexp_matching_top, transit_state_mb):
(transit_state_bkref, get_subexp, get_subexp_sub, find_subexp_node):
(check_arrival, check_arrival_add_next_nodes):
(check_arrival_expand_ecl, check_arrival_expand_ecl_sub):
(expand_bkref_cache, build_trtable, group_nodes_into_DFAstates):

(search_cur_bkref_entry, match_ctx_add_subtop, match_ctx_add_sublast):
(sift_ctx_init):
Likewise.
* lib/regex_internal.h:
(re_string_allocate, re_string_construct, re_string_reconstruct):
(re_string_realloc_buffers, build_wcs_buffer, build_wcs_upper_buffer):
(build_upper_buffer, re_string_translate_buffer, re_string_destruct):
(re_string_elem_size_at, re_string_char_size_at, re_string_wchar_at):
(re_string_context_at, re_string_peek_byte_case):
(re_string_fetch_byte_case): Declare even if RE_NO_INTERNAL_PROTOTYPES
is defined, since we now use prototypes always.
* lib/regex.h (_RE_ARGS): Remove. No longer needed, since we assume
C89 or better. All uses removed.
