Some of the oldest and cruftiest AT&T lexers do not support the
concept of an exclusive start state, which we use extensively (it's my
fault; makes for *much* cleaner specifications).
Unfortunately, Sun adopted some SysV packages when they made the
switch from BSD, and got a bad lexer in the bargain. afaik, most other
systems ship a more capable package.

Yes, that would probably be a good idea...
