Where is select() declared in your system headers?  Evidently we're
missing a #include, but I dunno which.

Assuming that this is freebsd, I've suppressed that warning.

This one probably ought to be directed to the BSD maintainers.

As Thomas pointed out, we can't do much about these without control
of the flex sources.  They've irritated me for a long time, since
they're the only build warnings I get.  It's interesting though that
our other flex files don't provoke these warnings.  Perhaps the
problem only occurs if the flex source file uses yylineno?

I think Hiroshi fixed this already.

This one's yours to fix ...

These are just tsort being noisy.  I'm not sure why we bother with
tsorting library member files any more anyway --- do any supported
platforms actually need it?
