i2c versioning

[phil at netroedge.com]

I think it's going to have to be converted in the Makefile and then
passed in as major, minor, etc. via -D's.  Not real pretty, but it's
effectively the same thing.  You can still do your #if's, but not
directly on the string constant.  It's surprising that strings can't
be compared by cpp...
