Re: [swarm-hackers] Swarm on MacOS 10.6 Snow Leopard

Adding -ansi can fix that, but is that what everyone else is doing?  And just out of interest, why do we have both K&R and non-K&R-style function prototyping?  Just evolved that way or there's a higher reason?

Okay, now have compilation down to 25 errors...

My first question is regarding the K&R style code, for example...

/* Copy SRC to DEST, returning the address of the terminating '\0' in DEST.  */

char *

stpcpy (dest, src)

     char *dest;

     const char *src;

{

  register char *d = dest;

  register const char *s = src;

  do

    *d++ = *s;

  while (*s++ != '\0');

  return d - 1;

}

...from swarm/src/misc/stpcpy.c

Why do we have K&R style code to begin with, and how do I configure Xcode to be K&R-compatible?
