Hi,

attached is a patch for the file djgpp/src/libc/dos/dos/gettimeo.txh to
make clear (hopefully), that gettimeofday() does not have microsecond
resolution

Best regards...
		Michael

  If either @var{tp} or @var{tzp} are @code{NULL}, that information is not
  provided. 
  
+ Note that although this function returns microseconds for compatibility
+ reasons, the values are accurate to less than 1/100 seconds only.
+ The underlying DOS function has 1/100 seconds granularity, but it is
+ calculated from the 55 ms timer tick count, so you won't get better than
+ that with gettimeofday().
