need windows help for launch command

[Ram B. <ra...@gm...>]

Hi,

I am working on a patch to extend launch (a clisp routine to launch
sub-processes) so that the environment of the child process can
be controlled from lisp. I think the unix side of the work is done.

However I know nothing about windows. If someone could look at this
and suggest how to make this work on windows that would be great.

I have tested the environment parameters and it works. I also tested
reading from the output stream of the launched command, that works.
I don't know enough about lisp to test the input stream.

Sam had these earlier comments:

>> 1. please read http://clisp.podval.org/impnotes/add-fun.html - you

>> 2. what about win32?

>> 3. when :environment is missing or :default, you should use execve

>>
>> 4. switching the existing functions to use launch will be done
>>    only after launch is made public and all the other
>>    functions are officially deprecated.
>>
>> 5. shell is NOT going away, ever, because it is immensely
>>    useful for things like (shell "cat foo | cut ... | awk | sed | perl ")
>>    which would be hard to implement in lisp.

>> Thanks for your work.

For 1 - This patch has changes to subr.d subrkw.d

For 2 - I am not able to do the win32 work, I need help.

For 3 - Done.

For 4 - Done - I have removed my changes to switch to the
new launch command.

For 5 - Done - shell is untouched.
