+ regex: merge glibc changes
+ Also, copy the license wording from glibc. This simplifies
+ merging changes. gnulib-tool will change the wording to GPL as
+ appropriate, when importing it to other packages. The only
+ glibc change made since the last merge, which needs merging, is:
+ 2012-05-24 Andreas Schwab <schwab@linux-m68k.org>
+ * lib/regex_internal.h (gettext): Remove use of INTUSE.
+
* users.txt: Add Emacs.
