A look a the output of "strings" shows that the compiler does appear to
optimize this. So your suggestion is probably the way to go.

One thing that isn't so nice about all this is that it embeds the
personal directory structure of the builder of the binary into the
shipped product. But gcc's cpp doesn't like redefining __FILE__, so the
only way to get around that altogether would be to use something other
than __FILE__ and define that for all builds. Might not be worth it.
