Because it isn't supposed to.

STAT(2)                   FreeBSD System Calls Manual                  STAT(2)
...
     #include <sys/types.h>
     #include <sys/stat.h>
     int
     stat(const char *path, struct stat *sb)
...

I believe that posix and/or ANSI-C (now ISO-C, soon to be C9x)
requires that name space polution be limited in what sys/stat.h can
cause to be defined.
