+
+Fri Apr 30 11:37:54 2010  Arnold D. Robbins  <arnold@skeeve.com>

+
+	* ltmain.sh: Removed.
+	* builtin.c (do_mktime): Restored old code to match the
+	documentation. We now have a warning that we just have to
+	live with. Sigh. Stupid GCC. Added a lint warning though.

+	without <locale.h>.
+	* main.c (main): Add `&& #if defined(HAVE_LOCALE_H)' for

+
+	* array.c (assoc_lookup): Add cast in error message to turn

+	* array.c, awkgram.y, builtin.c, dfa.c, eval.c, ext.c, main.c,

+
+Thu Apr  8 20:45:25 2010  Arnold D. Robbins  <arnold@skeeve.com>
+
+	Move dfa internals into dfa.c and sync with grep. Avoids VMS and
+	z/OS compile problems in order to avoid cygwin issue when used
+	with ligsigsegv.  ("Portability?  We don't need no stinkin'
+	portability!")
+
+	* dfa.h: Move all the internals into dfa.c.
+	(dfaalloc, dfamusts, dfabroken): Add declarations.

+	"not used" warnings.
+
+Tue Apr  6 20:11:47 2010  Arnold D. Robbins  <arnold@skeeve.com>
+

+	(in_coll_range): z/OS fix: Initialize array to all zeros and assign
+	values instead of putting them into the initializer. Thanks to Dave
+	Pitts for reporting the problem.
+
+Fri Apr  2 12:32:40 2010  Arnold D. Robbins  <arnold@skeeve.com>

+
+Mon Mar 29 05:38:47 2010  Arnold D. Robbins  <arnold@skeeve.com>
