----------------------------------------------------------------------------

1, When using time.h and the tm structure (eg GMT->tm_year), fails to 
   compile with errors simular to :-

   pom.c: In function `main':
   pom.c:91: warning: assignment makes pointer from integer without a cast
   pom.c:93: dereferencing pointer to incomplete type

   Check that you are using :- #include <time.h>
   and not                  :- #include <sys/time.h>

----------------------------------------------------------------------------

2, getcodi.c:39: sys/cdefs.h: No such file or directory

   Remove :-

   #include <sys/cdefs.h>
   #ifndef lint
   #if 0
   static char sccsid[] = "@(#)getcodi.c   8.1 (Berkeley) 5/31/93";
   #else
   __RCSID("$NetBSD: getcodi.c,v 1.4 1997/10/12 21:24:49 christos Exp $");   
   #endif
   #endif /* not lint */

----------------------------------------------------------------------------

3, damage.c:49: err.h: No such file or directory

   Remove :- #include <err.h>

   Change the lines using errx eg     errx(1,"Error with program");
        
   to use printf and exit eg          printf("Error with program");
                                      exit(1);

----------------------------------------------------------------------------

4, arithmetic.c:81: parse error before `__P'


   Change :-	int     problem __P((void));
		int	problem (void);

----------------------------------------------------------------------------

5,  Comment out all (or delete) 

    int argc __attribute__((unused));

----------------------------------------------------------------------------

6,   Change :-  #include <termcap.h>
         to :-  #include <term.h>
