Yep, very good point indeed. Not sure if there's any non-human intrusive 
solution to this case then. Since the files have to be there in the case 
users don't have flex/yacc. And it seems relying on the timestamps, even 
if equal, is pointless for the build to do in this case. About the only 
sure way of handling this would be to have a checksum file which the 
build can check against a computed checksum of the source files. Oh' 
well maybe for bjam4.
