Ugh, I hate when this gets out of sync...

Yep.

Yeah, there's a problem with the automatic conversion -- making it explicit to 
the type for the function (greg_weekday) does the trick for me on gcc-4.

     date d5 = next_weekday(d4, greg_weekday(Sunday));

For sure -- I noted a couple other things that prevent the 'cut from the docs, 
paste, and compile' technique from working.  Added to my todos.  Thx for the 
report.
