Compilation error fixes for older GCC/CLang compilers

Avoid data type re-declaration, it's not really working on current FreeBSD's 9
system and CLang-3.0 from OSX.

This is not a good idea to do such sort of copy-paste anyway.

If someone knows better way of dealing with this please go ahead and correct
the code :)
