File
deploy\src\common\windows\native\CJavaConsole.cpp
contains in 3 projects.
The same story with the rest of CPPs from deploy\src\common\windows\native\.

Each project has different settings (precompiled headers and etc.)
That makes changes in "shared" files incredibly tangled (I mean taken into account additional dependencies).
1. PLEASE, USE DYNAMIC OR STATIC LIBLARIES (DLL or LIB)!!!
2. Please, unify the byuildind system like common setup include + file list.
