Windows does have execve(), though it's named _execve(). Not sure if
that means it has slightly different behaviour than on Unix. See

tml/_crt__execve.2c_._wexecve.asp.
But looking at the code you will notice that win32 already does not use
system() - copydir() is available to do it internally. Haven't looked at
the details, but perhaps this can just be used straight off on Unix as
well.
From what I can tell, rm is also handled in the rmtree() function, and
not by system(), since version 1.138 of dbcommands.c.
