Re: Bison 1.35 is complied for Win32 with MSVC 6.0

[Akim Demaille]

| Hello all Bison users

Hi!

| Here is a patch to compile Bison v1.35 for Win32 platforms and use it as
| standalone application. Latest Bison already searches for bison.simple and
| bison.hairy datafiles in bison.exe startup directory and can be conveniently
| used separately but nevertheless some small fixes are required.

Sorry, but I will not install your patches, because they are way too
much much `Windows' oriented.  You submit more configure.ac things,
more replacement functions etc.  but not to add `#if MY_FAVORITE_ARCH'
patches.

Nevertheless, you are of course most welcome to distribute
pre-compiled version of Bison.

I don't understand, this ought to be taken care of by configure.  What
is the problem?


| Short README about this also attached.

This is great work!  I'm ready to put instruction into a new
directory, say arch/win32, but not in sources of Bison itself.  Sorry :(
