+Submitted by: Matt Burgess (matthew at linuxfromscratch dot org)
+Date: 2009-05-03
+Initial Package Version: 2.5.35
+Origin: Matt Burgess
+Upstream Status: Submitted (attached to sourceforge bug 2178663)
+Description: Fixes an error caused by header cleanups in GCC 4.4.0 that is
+             evident from the test suite and would affect any C++ lexers
+             generated by Flex.  Without this patch, Flex will generate lexers
+             containing references to the 'EOF' symbol without including the
+             necessary C++ header file, leading to:
+
+             error: 'EOF' was not declared in this scope
