+ * intl/dcigettext.c (DCIGETTEXT): Increment path_max proportionally.
+
+2001-10-31 Bruno Haible <bruno@clisp.org>
+
+ * intl/plural.y: Include <stddef.h>, needed for NULL with SunOS 4 cc.
+
+2001-03-21 Bruno Haible <bruno@clisp.org>
+
+ * intl/dcigettext.c (_nl_state_lock): Mark as #ifdef _LIBC. AIX 3 xlc

+ * intl/plural.y: Add #pragma for alloca on AIX 3.
+
+2001-11-27 Ulrich Drepper <drepper@redhat.com>
