* The `include' builtin now affects exit status on failure, as required by
POSIX. Use `sinclude' if you need a successful exit status.
+* A new `--warn-syntax' command-line option allows detection of
+ non-portable syntax that might be broken when upgrading to M4 2.0. For
+ example, POSIX requires a macro definition containing `$11' to expand to
+ the first argument concatenated with 1, rather than the eleventh
+ argument; and allows implementations to choose whether `${11}' is treated
+ as literal text, as in M4 1.4.x, or as the eleventh argument, as in the
+ eventual M4 2.0. Be aware that Autoconf 2.61 will not work with this
+ option enabled.
* Improved portability to platforms such as BSD/OS.
