+Changes from 2.15 to 2.15.1
+---------------------------
+
+Close stdout and stderr before all redirections on program exit.  This allows
+  detection of write errors and also fixes the messages test on Solaris 2.x.
+
+Removed YYMAXDEPTH define in awk.y which was limiting the parser stack depth.
+
+Changes to config/bsd44, Makefile.bsd44 and configure to bring it into line
+  with the BSD4.4 release.
+
+Changed Makefile to use prefix, exec_prefix, bindir etc.
+
+make install now installs info files.
+
+make install now sets permissions on installed files.
+
+Make targets added:  uninstall, distclean, mostlyclean and realclean.
+
+Added config.h to cleaner and clobber make targets.
+
+Changes to config/{hpux8x,sysv3,sysv4,ultrix41} to deal with alloca().
+
+Change to getopt.h for portability.
+
+Added more special cases to the getpgrp() call.
+
+Added README.ibmrt-aos and config/ibmrt-aos.
+

+From: karl@cs.umb.edu (Karl Berry)
+Newsgroups: gnu.utils.bug
+Subject: gawk 2.15/ibm rt/compile errors
+Date: 17 May 1993 23:16:11 -0400
+Organization: GNUs Not Usenet
+
+gawk 2.15 on an IBM RT running AOS, configured as bsd43, needs the
+following additional definitions (although I suppose this will be
+irrelevant when you switch to Autoconf).
+
+-DTZSET_MISSING -DFMOD_MISSING -DCHAR_UNSIGNED
+
+[ Fixed in 2.15.1 -- configure as ibmrt-aos ]
+
+Also, missing/strftime.c did not compile, because it does not handle the
+case where the system provides neither tzname nor the tm_zone member,
+but instead has the timezone function.  I used the strftime.c from the
+find 3.8 distribution.
+
+[ Not fixed in 2.15.1 ]
