Since mingw programs don't need Cygwin installed, these should
probably be OK for most Windows people.
But if really needed, flex 2.5.33 could be ported (m4 is already
ported).
I'm also wonderings why flex is a problem, since there is a GNUwin32
(native) port of Bison 2.4.1 and m4,
And Bison uses m4 these days, doesn't it? Perhaps it wouldn't be so
hard to update flex to use the same m4 calling that bison uses?
It is part of the MSys utilities, and requires that you have MSys
installed. MSys is in effect a Cygwin equivalent. The flex from MinGW
will NOT run standalone. I have tried.
If you think it can be ported to run standalone (i.e. without either
Cygwin or MSys), have at it. Or take my advice and don't waste time
trying.
What I have done is built a version of flex 2.5.35 with Cygwin, and
bundled the .exe with the Cygwin DLL (the only other thing it should
need, for our purposes) in a zip file. It can currently be fetched from
<http://developer.postgresql.org/~adunstan/windows-flex-2.5.35.zip>.
That way people won't have to do a full Cygwin or MSys install to use it.
