[swarm-hackers] Swarm on MacOS 10.6 Snow Leopard

[Bill Northcott]

I finally got around to trying to do a new MacOS build of Swarm.   
Sorry about the delay but as soon as the shoulder got well enough I  
had a much postponed knee repair and the pain killers were trashing my  
head.

As I am now armed with a spiffy new 8-core MacPro running Snow Leopard  
I am going for the full bleeding edge build.

I pulled down the current svn HEAD and tried building using Scott's  
Xcode project.  After a few simple fixes I have a problem with the  
misc functions.

In particular src/misc contains replacements for a number of string.h  
functions including stpcpy.c.  It seems that on Snow Leopard stpcpy()  
is a macro.  So the preprocessor mangles stpcpy.c into:

char *
((__builtin_object_size (dest, 0) != (size_t) -1) ?  
__builtin___stpcpy_chk (dest, src, __builtin_object_size (dest, 2 >  
1)) : __inline_stpcpy_chk (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;
}

The compiler likes this not at all.

As a quick perusal of the remaining 1800+ build errors indicates that  
this is not the only similar issue.  Is there some compelling reason  
not to use the OS provided functions?
