make the DOMinator code compile on 64-bit Linux and newer compiler chain

[dmitris]

Fedora 17 is 64-bit Linux, would be great to be able to compile DOMinator on it with a newer compiler toolchain (such as gcc-4.7). Some code changes (in the stock FF code, unrelated to the tainted part) would be needed.
