Yes. There is some trickiness in 10.4's errno.h:


% cat /usr/include/sys/errno.h
...
#define ENOTSUP         45              /* Operation not supported */
#if !__DARWIN_UNIX03 && !defined(KERNEL)
/*
  * This is the same for binary and source copmpatability, unless  
compiling
  * the kernel itself, or compiling __DARWIN_UNIX03; if compiling for  
the
  * kernel, the correct value will be returned.  If compiling non-POSIX
  * source, the kernel return value will be converted by a stub in  
libc, and
  * if compiling source with __DARWIN_UNIX03, the conversion in libc  
is not
  * done, and the caller gets the expected (discrete) value.
  */
#define EOPNOTSUPP       ENOTSUP        /* Operation not supported on  
socket */
#endif /* !__DARWIN_UNIX03 && !KERNEL */

...

#if __DARWIN_UNIX03 || defined(KERNEL)
/* This value is only discrete when compiling __DARWIN_UNIX03, or  
KERNEL */
#define EOPNOTSUPP      102             /* Operation not supported on  
socket */
#endif /* __DARWIN_UNIX03 || KERNEL */
