I compiled what I believe is actual lex on Linux.  There were two compile
time errors to fix, and a bunch of warnings that I didn't fix.

The warnings are related to pointer conversions, so I hope it
does it right.

I then ran it with the sample program in the Wikipedia lex article,
and it ran out of buffer space.  It isn't very big, either.

But then I ran it with the sample from the Solaris lex man page,
and it works.  It even works with -r to generate ratfor output.
(As far as I know, flex doens't have the -r option.)

In any case, I don't understand the buffer space message.

size buffers. -John]
