Yuck! I hate adding requirements like that on users. It's bad enough
that we now require GNU make, and still have a lot of difficulty with
non-GNU compilers. You shouldn't need to replace all your development
environment with GNU tools just to compile a program. I'd rather insist
on at least attempting to write portable code before shifting the burden
on users like this.
Is there any way I can convince you to go back to lex and try the
two simple code changes I suggested? I was really hoping to get some
portability feedback here.
