[PATCH] Remove obsolete reference to <sys/_posix.h>

Hi,

while doing some porting work I found that in src/sys/posix4/mqueue.h we 
still include sys/_posix.h, despite having removed the relevant file in 
2002. This tiny patch should fix this:

--- /usr/src/sys/posix4/mqueue.h        Sat Sep 21 21:49:56 2002
+++ mqueue.h    Tue Jul 13 15:59:12 2004
_at__at_ -37,8 +37,6 _at__at_
  #ifndef _MQUEUE_H_
  #define        _MQUEUE_H_

-#include <sys/_posix.h>
-
  #ifdef _P1003_1B_INCLUDE_MAYBES
  #include <sys/types.h>
  #include <fcntl.h>


Cheers,
