I replaced the gcc-4.3 compiler with a gcc-4.6.3 compiler and the 
duplicates errors disappeared.

The following patch works with both the gcc-4.3 and gcc-4.6 compilers.

Beyond the duplicates, the header and libxfs files in 
thexfsprogs-kernel-3.8-update patch compare to Linux 3.8 kernel code and 
I consider it Reviewed-by: me.

I will do the xfsprogs-kernel-3.9-rc1-dev-update tonight.

--Mark.
