+       Make regex safe for g++.  This fixes one real bug (an "err"
+       that should have been "*err").  g++ problem reported by
+       Sam Steingold.
+       * regex_internal.h (re_calloc): New macro, consistent with
+       re_malloc etc.  All callers of calloc changed to use re_calloc.
+       * regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t,
+       not int.  All callers changed.
+       * regcomp.c (re_compile_fastmap_iter): Don't use alloca (mb_cur_max);
+       just use an array of size MB_LEN_MAX.
+       * regexec.c (push_fail_stack): Use re_realloc, not realloc.
+       (find_recover_state): Change "err" to "*err"; this fixes what
+       appears to be a real bug.
+       (check_arrival_expand_ecl_sub): Be consistent about reg_errcode_t
+       versus int.
