I must warn you, Windows will be really hard (as in "patching GCC" hard).

This is actually not GCC, it is Apple's Clang pretending to be GCC.

To build ODB from source on Mac OS you will need to build GCC with plugin
support enabled (--enable-plugin configure option). You could also try
GCC from homebrew though I am not sure if it's built with plugins enabled
these days.
