+** Fix regression introduced in 1.4.4b where using `traceon' could delete

+** Fix regression introduced in 1.4.11 where `defn' died with an assertion

+
+** New `-g'/`--gnu' command-line option overrides `-G'/`--traditional'.
+   For now, the environment variable POSIXLY_CORRECT has no effect on M4
+   behavior; but a future release of M4 will behave as though --traditional
+   is implied if POSIXLY_CORRECT is set (this future change is necessary,
+   because in the current release, there is no way to disable GNU
+   extensions that conflict with POSIX without the use of a non-POSIX
+   command-line argument).  Clients of M4 that want to use GNU extensions,
+   even when POSIXLY_CORRECT is set, should start using the -g command-line
+   argument, even though it is currently a no-op if -G did not appear
+   earlier in the command line, so that the client will not break in the
+   face of an upgraded m4 and a POSIXLY_CORRECT execution environment.
+
+** The `-L'/`--nesting-limit' command-line option now defaults to 0 for
+   unlimited on platforms that can detect and deal with stack overflow.  On
+   systems that lack alternate stack support, such as Cygwin, and on
+   systems that do not obey the POSIX semantics for distinguishing stack
+   overflow from other exceptions, such as Linux, you can optionally
+   install the libsigsegv library (version 2.6 or newer recommended) to
+   enhance m4's ability to accurately report stack overflow:
