+ update-copyright: avoid copyright notice date corruption
+ Given a sequence of copyright year numbers in which the final
+ one was a two-digit number that happened to be a substring of
+ a preceding four-digit year number, we would mistakenly update
+ the substring (from two- to four-digit) rather than the two-digit
+ number at the end, which, combined with the addition of the current
+ 4-digit year number would yield two 5-digit year numbers, e.g.,
+ here, it would convert the first "99" to "1999, 2013" rather than
+ the final one:
+ 1991, 99
+ 11999, 20131, 1999
+ * build-aux/update-copyright: Tighten a regexp.
+ * tests/test-update-copyright.sh: Add a test case to trigger the bug.

+ regex: omit needless signed-pointer casts
+ * lib/regcomp.c (build_charclass, build_charclass_op):
+ Use char *, not unsigned char *, for class name and extra.
+ The char values are always nonnegative so there's no need to
+ insist on unsigned char * here, and using char * removes the need
+ for casts. Reported by Aharon Robbins in
+ <http://sourceware.org/ml/libc-alpha/2012-12/msg00456.html>.
+
+ regex: support Gawk, which never uses alloca
+ * lib/regex_internal.h [!_LIBC && !HAVE_ALLOCA]:
+ Do not include in this case. Gawk doesn't supply a substitute
+ alloca.h and doesn't need one.
+
+ regex: port __libc_lock_define usage to C89
+ * lib/regex_internal.h (__libc_lock_define) [!_LIBC]: Remove.
+ (struct re_dfa_t): Use #ifdef instead. '__libc_lock_define (, lock)'
+ does not conform to C89, as it has an empty macro argument.
