That's just a documentation glitch, surely; CLK_TCK is the same thing as
sysconf(_SC_CLK_TCK), other than its deprecatedness.  My linux times(2)
manpage says:

NOTES
       The number of clock ticks per second can be obtained using
              sysconf(_SC_CLK_TCK);
       In POSIX-1996 the symbol CLK_TCK (defined in <time.h>) is
       mentioned as obsolescent. It is obsolete now.

A platform-specific documentation error doesn't make the function useless,
especially when the function in question is defined by a standard which,
presumably, doesn't make the same error ...

Don't forget -W, which enables several other useful warnings not
included in -Wall.
