* This file exists because #include file definitions aren't in the same
* place on all machines. Also, it seems pointless to drag in all of
* <stdio.h> just to define NULL. Finally, a few declarations are
* sufficiently global that this is the most logical place to put them.
*
* This file should be #included after all of the system include files
* (e.g. <sys/types.h>) but before any other UW include files.
