The libc.inf "delay()" node is missing the #include <dos.h> line to indicate which header file to include to get delay.

Here's a patch to the file /src/libc/dos/dos/delay.txh.

*** delay.tx~	Mon Jul 10 01:40:08 1995
--- delay.txh	Sat Nov 30 00:35:48 1996

*** 2,7 ****

  @subheading Syntax
  
  @example
+ #include <dos.h>
+ 
  void delay(unsigned msec);
  @end example
