I don't know if we've ever made an official decision on this ... but my feeling has been that requring flex and/or bison is fine. Automake sets up things so when a distribution is created the C language files produced by flex and bison are distributed so there is no requirement to have the GNU variants to build nmh. You would need them to build from the repository, though. I realize this is something reasonable people can disagree on, so I am welcome to hearing what others think about this. --Ken
