Patch #1019808 from Federico Schwindt: Return correct socket error when

a default timeout has been set, by using getsockopt() to get the error
condition (instead of trying another connect() call, which seems to be
a Linuxism).

2.5 bugfix candidate, assuming no one reports any problems with this change.
