Description:
------------
gethostbynamel test 
ext/standard/tests/network/gethostbynamel_error.phpt should use 
canonical name for the "Testing gethostbynamel() with an unknown 
host" test:

var_dump(gethostbynamel("unknownhost_zzz_xxx_yyy"));

unknownhost_zzz_xxx_yyy may be expanded to  
unknownhost_zzz_xxx_yyy._your_local_domain_ and resolv correctly, in 
which case the test fails, even if it is actually not a bug.

The test may use a canonical name (a dot at the end for the name), 
so that it will not be expanded, and never resolv:

var_dump(gethostbynamel("unknownhost_zzz_xxx_yyy."));
