Emacs solution

except for the fact that having version 100 be released in 2100 makes a lot more sense than 100 being the year 2000 did.

making the version be year-2000 will take us to 2255, which is long enough for that field to be expanded to more than 8 bits.

besides, don't you know that everything will be re-done by 2038 anyway when time_t runs out? that's the date to worry about, not 62 years later.
