(optimize_subexps, lower_subexp):

have to worry about portability issues when shifting it left.
Remove no-longer-needed test for table_size > 0.
* lib/regcomp.c (parse_sub_exp): Do not shift more bits than there are
in a word, as the resulting behavior is undefined.
* lib/regexec.c (check_dst_limits_calc_pos_1): Likewise;
in one case, a <= should have been an <, and in another case the
whole test was missing.
* lib/regex_internal.h (BYTE_BITS): Remove.  All uses changed to
the standard name CHAR_BIT.
* lib/regexec.c (match_ctx_add_entry): Don't assume that ~0 == -1;

* lib/regcomp.c, lib/regex_internal.c, lib/regex_internal.h:
* lib/regexec.c:
All uses of recently-renamed identifiers changed to use the new,
POSIX-compliant names.  The code will build and run just fine

Remove glibc bug 1233 and add 1236, which supersedes it.

* lib/regex.h: Fix a multitude of POSIX name space violations.
These changes have an effect only for programs that define
_POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
do not change anything for programs compiled in the normal way.
Also, there is no effect on the ABI.

(_REGEX_SOURCE): New macro.
Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
defined and _GNU_SOURCE is not; this fixes a name space violation.

Rename the following macros to obey POSIX requirements.
The old names are still visible as macros if _REGEX_SOURCE is defined.
(REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from

(REG_DEBUG): renamed from RE_DEBUG.
(REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
(REG_IGNORE_CASE): renamed from RE_ICASE.  This renaming is a bit
unusual, since we can't clash with the POSIX REG_ICASE.
(REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
(REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.

(REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
(REG_DUP_MAX): renamed from RE_DUP_MAX.  No need to undef it.

(REG_REALLOCATE): Renamed from REGS_REALLOCATE.
(REG_FIXED): Renamed from REGS_FIXED.
(REG_NREGS): Renamed from RE_NREGS.

(REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
of other REG_* macros, since POSIX says the user is allowed to
#undef these macros selectively.

(reg_errcode_t): Update comment stating what other tables need
to be consistent.

Rename the following enum values to obey POSIX requirements.
The old names are still visible as macros.
(_REG_ENOSYS): Renamed from REG_ENOSYS.  Define even if _XOPEN_SOURCE
is not defined, since GNU is supposed to be a superset of POSIX as
much as possible, and since we want reg_errcode_t to be a signed
type for implementation consistency.
(_REG_NOERROR): Renamed from REG_NOERROR.
(_REG_NOMATCH): Renamed from REG_NOMATCH.
(_REG_BADPAT): Renamed from REG_BADPAT.

(REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN):
(REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
(REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.

(_REG_RE_NAME, _REG_RM_NAME): New macros.
(REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE.  All uses
changed.  But support the old name if the new one is not defined
and if _REGEX_SOURCE.

Change the following member names in struct re_pattern_buffer.
The old names are still supported if !_REGEX_SOURCE.
The new names are always supported, regardless of _REGEX_SOURCE.

(re_not_eol): Renamed from not_eol.
(re_newline_anchor): Renamed from newline_anchor.

Change the following member names in struct re_registers.
The old names are still supported if !_REGEX_SOURCE.
The new names are always supported, regardless of _REGEX_SOURCE.
(rm_num_regs): Renamed from num_regs.
(rm_start): Renamed from start.
(rm_end): Renamed from end.

* config/srclist.txt: Add glibc bug 1233.
* lib/regex.h (REG_NOSYS)
[!defined _XOPEN_SOURCE && 200112L <= _POSIX_C_SOURCE]:
Define, since POSIX requires it as of 2001.
(_REG_ENOSYS) [! (defined _XOPEN_SOURCE || 200112L <= _POSIX_C_SOURCE)]:

assumed that reg_errcode_t is a signed type, which is not
necessarily true if _XOPEN_SOURCE is not defined.

* config/srclist.txt: Add glibc bug 1226.
