The error code in this case is clearly wrong. It seems to be triggered by
the inability to find the home directory in which the netrc file, and in
this case it should be treated like the file was not found. Does this patch
work for you?


diff --git a/lib/netrc.c b/lib/netrc.c

The patch you suggest would allow the code I'm working on to function
however if you consider the case where use_netrc is set to
CURL_NETRC_REQUIRED this would lead to a successful return from
override_login if home is not found in netrc.c. I'm not sure if anyone is
counting on it returning a failure in this case but you can see the logic.
