I think we're already putting more energy into this than it deserves :)
At least for blocks, gr_modtool creates header guards that consist of
the module- and the block name, which you should choose wisely anyway.
Little chance of collisions here.

A script that would check for unique header guards wouldn't hurt. But
what are "optimizable guards"? I think we have much bigger cookies to
bake right now.
