The source file should include "sys/types.h", but it doesn't. (To the
original author: typedef'ing "socklen_t" to be "int" is not a solution.
Passing a pointer to your home-made type to a library function is
dangerous, since nobody gurantees that the "socklen_t" of the C library and
your definition have the same size. "man recv" explicitly says that both
"sys/socket.h" and "sys/types.h must be included.

I guess including "sys/types.h" will fix the problem for you. Please try it
and report if it did so that we can fix this bug in CVS.
