Patch tape: changes to include files

[Andrew J. Schorr]

I have finally applied the patch, and I noticed some
strange changes to include files.  In <sys/time.h> and
<sys/ioctl.h>, there are 2 #ifdef's based on a new (to me)
preprocessor symbol: _BSD_INCLUDES.  It was my understanding
that _BSD was the appropriate symbol to define for BSD
compatibility.  Should I be defining _BSD_INCLUDES as well,
or is this a screw-up?
