Your package fails to build with GCC 4.4, which has cleaned up some more
C++ headers. You always have to #include headers directly and cannot
rely for things to be included indirectly.
You can reproduce this problem with gcc-snapshot from unstable or
gcc-4.4 from experimental.

thanks for the patch, just applied this as a workaround to upstream svn.
Imo the real bug seems to originate in the c++ code generated from flex, which
uses EOF (the .l file doesn't) but doesn't issue the necessaring include,
hence cloning the bug to flex.
Cheers,
Stefan.
