>Description:
In <sys/stat.h>

#if !defined(_POSIX_C_SOURCE) && !defined(_XOPEN_SOURCE)
#define S_ISSOCK(m)     ((m & _S_IFMT) == _S_IFSOCK)    /* socket */
#define S_ISWHT(m)      ((m & _S_IFMT) == _S_IFWHT)     /* whiteout */
#endif

but by my reading of the standard @ 

http://www.opengroup.org/onlinepubs/007904975/basedefs/sys/stat.h.html

It says that S_ISSOCK should be defined. 

>How-To-Repeat:
Well I noticed when I was building rdiff-backup; it will fail because </usr/pkg/include/python2.3/pyconfig.h> has defined _POSIX_C_SOURCE for  __NetBSD_Version__ < 106200000.  
>Fix:
Unproect these macros from !defined(_POSIX_C_SOURCE)
