windows translation lib
Peter MacDonald
compile Windows programs under Linux without code changes.
It is really just a proof of concept, to show how easy it is.
First off, I have never programmed in windows, and probably never
will. I have done a little bit of XV programming a year or
two ago, but am very rusty. I am still trying to dig up
all the old code I wrote. All the Windows constants are wrong, and
I will get the proper windows.h, or clean-room one from the
MS Blue Book eventually.
I am also not even sure that XV should be used as the base. I
am not very X literate. Nevertheless, I did this to demonstrate
how easy it could be to do. Let me know if you can help.

I have created a mail channel called WABI where Windows under linux
issues can be discussed. A number of people have written me expressing
interest in these sorts of things, and it seemed like a good idea to take this
discussion to a mail channel and spare c.o.l. the extra bandwidth.
To join the channel, send mail to
linux-activ...@joker.cs.hut.fi, with the line:
X-MN-Admin: join WABI
in the header of the message.

Peter, does this mean you're throwing your gauntlet into
the ring? If someone actually starts working on it, instead
of talking, I might have to revise my estimates :-)
By the way, Peter--and I don't do this out of ego--your "credits"
list showed Matthias Lautner to be the author of dosemu. While
this is true for version 0.4 and earlier, I have made what
I believe are significant contributions, as well as becoming the
new maintainer. Perhaps I could be co-listed so that people know
where to send the hate mail?

Well, I guess so. I have already done a bit a work. I now have
a windows.c file that will allow you to compile and link and run any
windows program (theoretically). Unimplemented functions just
print out a message that they were called. The MS-windows hello-world
program runs, under xview. I suggest that we just continue on by
compiling successively more complex windows progs and implementing the
reportedly missing functions. We still have to decide wether to
use xview or not. It looks so much nicer.

I can't believe how much response I am getting this time. Last time,
a few months ago, all I got was a trickle.
Consider yourself added.
