--- Comment #7 from Paolo Bonzini bonzini@gnu.org 2010-04-11 16:44:05 --- Exactly why? If it is not supported to call Unix programs from Windows, the bug is that you can spawn a Unix program in the first place.
Otherwise it is supported, and spawnl(P_WAIT, "...") not waiting is a bug.
In either case, there is a bug. Also, closing as "FIXED" is wrong. It could be "INVALID" or "WONTFIX", but it is not fixed.
