Here's an example of a program that didn't
compile under 4.2/4.3bsd (VAX). The program DID
compile on a SUN, or with the portable C compiler
under SUMacC.
#define NKEYS 20
typedef union {
unsigned char *bytes;
unsigned long *words;
} block;
main()
{
block sched[NKEYS];
int i;
i= 4;
bar(i, sched);
}
bar (i, sched) block sched[];
{
foo(sched[i]);
}
foo (junk) block junk;
{
printf("%d\n",junk.bytes);
}
