Compiler warnings shown as ERROR log level

The compile warnings should be logged as warning log level (if it is possible). It will help to find the real errors.

Here is an example:

[ERROR] /projet/xmlrpc.net/target/build-sources/main-sources/XmlRpcClientProtocol.cs(980,14): warning CS0219: The variable `coen' is assigned but its value is never used
