Here is a patch to support "w32_error" for assuan_sock_get_flag function.

It's a bug I introduced when fixing T7309.
Fixed in rGaa36f6ae8bae: gpg: Fix key generation with existing key from card.

@uwi: We removed the ciphersuite from the server and tested with 4.2.0 that you get an update notification now. Because of some caching you may need to

(ignore the last commit, I assigned the wrong task to it)

This is due to an update of the server providing the version info. The server (Apache) uses a smaller hash than the ECC key. This is allowed behaviour and was fixed in our TLS library in 2022; see T6059. However, the new library was released only early this year an. We will check whether we can tell our Apache to use a more correct hash algorithm.

What do you thing of storing the last WSAGetLAstError value also in the context and extend assuan_sock_get_flag to return this error value? The thing here is that I fear the mapped information is not enough to find the problem with the bind call.
