[uClibc-cvs] uClibc/libc/inet resolv.c,1.44,1.45

[Erik Andersen]

Update of /var/cvs/uClibc/libc/inet
In directory winder:/tmp/cvs-serv10056/libc/inet

Modified Files:
	resolv.c 
Log Message:
Patch from Jeffrey Damick:

With glibc if you do a res_init() that forces a reread of the nameservers file,
but in uClibc the res_init will not force a reread if it has already read the
file because then the nameservers value is greater than 0.

So res_init must call close_nameservers() before calling open_nameservers().
