+** scanner
+
+*** several bug fixes resolved problems introduced in recent flex
+    versions regarding processing of comments, literals and various
+    quoting scenarios.
+
+*** If the path to m4 was sufficiently long, a buffer overflow could
+    occur. This has been resolved. The fix also removes dependence on
+    the constant PATH_MAX.
 
 ** build
 
+*** A new configure option --disable-bootstrap changes the behavior of
+    the build system when building flex. The default
+    "--enable-bootstrap" behavior is to build flex, then to use that
+    flex to build flex again. With --disable-bootstrap, the scanner is
+    simply built by sedding the scanner source. This is friendlier to
+    cross compilation.
+
 *** The compatibility functions in lib/ are no longer built as a
     library. Instead, they are built as $(LIBOBJ) objects. This is
     simpler and friendlier to cross compilation.
