Re: [Flex-help] History of the reentrant option

[Tim G. <ti...@de...>]

I'll look into what it takes, but there is a gnuwin32 project which
ports gnu utilities to windows using mingw as the compiler I think.  In
that project flex is listed as one of the utilities and as I mentioned
the version is 2.5.4a.

When I get a few minutes I will see what it takes to compile flex under
windows with Microsoft's compiler.

There is only one flex project. There's not a separate Windows and Unix
version.

We don't go out of our way to make flex non-portable, but we do assume
things like POSIX compliance. (Which makes sense given that lex is
defined by a POSIX standard and flex in its turn is based on the idea of
lex, allbeit with a number of extensions.)

If you can provide patches and the like to provide Windows portability,
I'm open to that, but as I'm not a Windows developer, I can only get
minimal testing for such things.
