 * WARNING: Future backward-incompatibilities!
 
+  - Makefile recipes generated by Automake 2.0 will expect to use an
+    'rm' program that doesn't complain when called without any non-option
+    argument if the '-f' option is given (so that commands like "rm -f"
+    and "rm -rf" will act as a no-op, instead of raising usage errors).
+    Accordingly, AM_INIT_AUTOMAKE will expand new shell code checking
+    that the default 'rm' program in PATH satisfies this requirement, and
+    aborting the configure process if this is not the case.  This behavior
+    of 'rm' is very widespread in the wild, and it will be required in the
+    next POSIX version:

   - Automake 2.0 will require Autoconf 2.70 or later (which is still
     unreleased at the moment of writing, but is planned to be released
     before Automake 2.0 is).
