[PATCH 0/2] MR6009: Allow building modules with C++ source

[Grigory Vasilyev (＠h0tc0d3)]

I believe that using CPP files in core Wine code is not a good idea. But it would be nice to have the option to compile C++ modules. For example, lsteamclient from Proton is written partially in C++.

Based on @rbernon patch.
