Subject: <time.h> & <sys/time.h>

 
Recently while trying to port some clients from Unix across to DV/X, I
noticed something strange in the DJGPP v1.09 time.h & sys/time.h includes ;
 
In <sys/time.h> ;
 
/*  (copyright stuff deleted)
*/
 
#ifndef _SYS_TIME_H_
#define _SYS_TIME_H_
 
#include <time.h>
 
struct timeval {
  long tv_sec;
  long tv_usec;
};
 
#ifndef _TIME_H_
struct timezone {
  int tz_minuteswest;
  int tz_dsttime;
};
#endif
 
#endif
 
 
You'll notice that struct timezone is only defined if _TIME_H_ isn't.
But examination of <time.h> shows that _TIME_H_ never gets #undef'ed.
Which seems to imply that struct timezone never gets declared, ever?

I couldn't agree more. I think DV/X and DJGPP are the best things to
happen to Unix/MS-DOS users in a LONG time.
