Is because the grammar spec usually is not a DAG?
It's straightforward to do something "dumb" (just pasting chunks of files together, a la #include), but I would like to explore better approaches. Bison is 30 years old, it can wait a bit more :) >> I'm worried though: this file is has plenty of K&R C, yet Bison >> generates parsers in ANSI C.

My point is: what's the point of keeping K&R if in practice ISO-C is required because of Bison. My worry being: maybe they don't want to use recent features of Bison but limit themselves to what older versions of Bison, that generate K&R compliant code, supported. _______________________________________________ help-bison@gnu.org https://lists.gnu.org/mailman/listinfo/help-bison
