>Environment:

3.0-CURRENT only, stable doesn't have this problem.

>Description:

<sys/time.h> uses some types from <sys/types.h> which aren't defined
under _POSIX_SOURCE, and doesn't protect the relevant sections with
#ifndef _POSIX_SOURCE.

>How-To-Repeat:

$ cat >test.c
#define _POSIX_SOURCE
#include <sys/time.h>
^D
$ gcc test.c
In file included from test.c:2:
/usr/include/sys/time.h:120: parse error before `timecounter_get_t'
/usr/include/sys/time.h:120: warning: data definition has no type or storage class
/usr/include/sys/time.h:125: parse error before `timecounter_get_t'
/usr/include/sys/time.h:125: warning: no semicolon at end of struct or union
/usr/include/sys/time.h:142: parse error before `}'

>Fix:

I don't have access to the POSIX spec, so I have no idea what the
right thing to do is.  Here's a guess:

*** time.h~	Wed Feb 25 16:47:38 1998
--- time.h	Fri Feb 27 10:02:46 1998
***************
*** 116,121 ****
--- 116,123 ----
   *     called attoseconds, it comes from "atten" for 18 in Danish/Swedish.

+ #ifndef _POSIX_SOURCE
+ 
  struct timecounter;
  typedef u_int timecounter_get_t __P((struct timecounter *));
  typedef	u_int64_t timecounter_delta_t __P((void));
***************
*** 140,145 ****
--- 142,148 ----
  	struct timecounter	*other;
  	struct timecounter	*tweak;
  };
+ #endif /* !_POSIX_SOURCE */
