>Description:
        The manpage for select lists three necessary include files:
unistd.h, sys/types.h, and sys/time.h.  Included in sys/types.h are the
related macros FD_SET, FD_CLR, FD_ISSET, FD_COPY, and FD_ZERO.  FD_COPY
and FD_ZERO are defined using memcpy and memset, which are prototyped
in string.h.  Since string.h isn't included by sys/types.h, programs
must explicitly include string.h.

>How-To-Repeat:
        Write such a program, build with -Wall, observe compiler
warning.
>Fix:
        Either update the select manpage to list string.h, or include
string.h from sys/types.h.
