execvp returns after exec.....

Yes, I looked into it and spawn with a wait would do the trick. (It
appears exec is some form of asynchronous spawn). However, I have one
problem; spawn will only take 1K max size argument list and in some
cases this is not enough. Any ideas on how to work around that?

Use spawn() instead of exec(). Pids differs because getpid in mingw
environment returns Win32 pid, and you have two _different_ win32
processes.
