Or you can create the batch file, run it and than remove it directly from C/C++. IE: create a new file in %TMP% or %TEMP%, write appropriate "set" commands into it, than run %COMSPEC% on it and then unlink (remove) it.

Ugly, but will probably work. I used something along these lines once. Although for my own use, so it wasn't important how crappy the code is if it does the job. :)
