Issues with IRC winsock DLL

See more:

C++

The issue is rather simple when I try to compile a DLL with winsock code it produces a huge number of errors. This does not happen when it is compiled as a console app and reason as to why are beyond me. If anyone has advice please give it.

A small fraction of them below

Moving the includes around in accordance with other threads made on this subject.
