auth_gssapi_client loading issue.

When I try to use the 'auth_gssapi_client.dll' that was packaged with MariaDB 10.1.19 I get an error, but if I use the 'auth_gssapi_client.dll' thats packaged with the 32bit portable version of HeidiSQL I can connect with my gssapi user just fine.

The error text is as follows (image attached)

[ma-3.0.5]Plugin auth_gssapi_client could not be loaded:
Library path is 'C:\Program Files (x86)\MariaDB\bin/auth_gssapi_client.dll'

As stated above, replacing the 'auth_gssapi_client.dll' with the the one packaged with the 32bit portable verison of heidi fixes this issue and allows me to connect.

I'm thinking this could be an architecture issue, but I'm not sure.
