AFAIK, you have to code this in a Makefile > somewhere. It can't. So you shouldn't depend on yacc taking an extra argument. 8-). > All I am suggesting is that src/Makefile should to a 'uname -r' and > build a few extra programs (make, yacc, ld) early depending on > 2.2.5-RELEASE, 2.2.6-STABLE or 3.0-CURRENT. An argument dependency is a relatively stick wicket. It is best to stay away from them. For this specific example, this would mean that, even though yacc can take a "-o", the FreeBSD build process should not depend upon there being a yacc that can take a "-o" installed. Alternately, the .mk should test for Yacc's capability before depending on it. Either way, you end up with a makefile that doesn't need "-o" as an argument to yacc, and a more complicated makefile that takes more time to run in the case that you want-to-use-but-can't-depend-upon a "-o".
