Agreed. This portion of bison output stems back to K&R days, when you couldn't guarantee things like malloc's declaration.

But given that more than a year ago, Bison was debating about switching to generating code that assumes C89 or better[1], this is yet another argument in favor of moving in that direction - by completely dropping the malloc() declaration and instead relying on <stdlib.h> to do it's job, this problem will be trivially avoided.
