Yes. If fds>2 will not be inheritted on spawn, it will be easy to create 
pipelines with spawn calls. Look at pexecute.c in egcs sources for _WIN32 
but no __CYGWIN32__ case (mingw32?). I'm not sure that gcc will work 
properly if cpp will terminate due to some error (spawned ΣΣ1 will inherit 
last_pipe_input and will never receive EOF!). The compilation will just 
hangs...
