I can't, because I need to redirect child I/O onto a socket, which 
requires CreateProcess. The Unix code is (relatively) easy, but it's a 
complete nightmare in Windoze. You have to use pipes as well as sockets, 
it has to be multi-threaded, select doesn't work, and so on.

I can use 'system' occasionally, but then I have the issues of 
forward/backslashes, extra backslashes, quotes, and so on. I haven't 
really got to the bottom of this. With CreateProcess I at least have the 
option to use /bin/sh, if it exists, which makes life a little easier 
(particularly for quote characters).
