[PATCH] rexec's 2nd argument should be network order

[Jakub Jelinek]

Hi!

In glibc 2.1.x, the rport argument from rexec is passed directly into
sin_port (ie. it is network byte order), similarly Irix manpage for exec
suggest using getservbyname("exec","tcp")->s_port to be passed as second
argument to rexec.
But in current CVS we snprintf it into buffer and if I understand right
getaddrinfo later on does a strtoul on this, converts the result using
htons() and passes that into sin_port.

	* inet/rexec.c (rexec_af): Convert rport to host order before
	passing it to snprintf.
