(prolog_pr): Cast strlen to int before comparison.
(LOOKING_AT, LOOKING_AT_NOCASE): Let the preprocessor check that
the second argument is indeed a literal string.
(longopts, print_help, main): The -a (--append) option
can be used in ctags also; for one, the Linux make file uses it.
* Makefile.in (AUTOCONF_INPUTS): New macro.
($(srcdir)/configure, $(srcdir)/src/stamp-h.in): Depend on it,
so that these files also depend on m4/getopt.m4.
* configure.in: Configure getopt by including m4/getopt.m4,
and configuring a getopt replacement if necessary.
* make-dist: Add m4 subdirectory. Unlink lib-src/getopt.h.
* m4/getopt.m4: New file.
* lib-src/Makefile.in (mostlyclean): Remove getopt.h, getopt.h-t.
(GETOPT_H): New macro, from gnulib.
(getopt.h): New rule, from gnulib.
(GETOPTOBJS): Now autoconfigured.
(GETOPTDEPS): getopt.h is now autoconfigured.
(getopt.o, getopt1.o): Depend on $(GETOPT_H), not ${srcdir}/getopt.h.
(getopt.o): Depend on ${srcdir}/gettext.h.
(movemail.o): Depend on $(GETOPT_H).
* lib-src/getopt.c, lib-src/getopt1.c: Sync from gnulib.
* lib-src/getopt_.h, lib-src/getopt_int.h, lib-src/gettext.h:
New files, from gnulib.
* lib-src/getopt.h: Removed (now is getopt_.h).
* nt/inc/gettext.h: Remove; no longer needed now that
lib-src/gettext.h exists.
* src/s/cygwin.h (C_SWITCH_SYSTEM): Remove, since gettext.h is
now part of lib-src.

(xmalloc): Likewise.
<stdlib.h> is available.

__attribute__ keyword, removed all the st_C_typespec keywords,
changed attribute for Java to (C_JAVA & !C_PLPL).
(inattribute): New global bool, part of the C state machine.
(cblev): Identifier renamed to bracelev throughout.
(consider_token, C_entries): Numerous changes for making the
parser more robust and adding support for __attribute__.
