FreeRDP/libfreerdp/core/gateway/tsg.h
Armin Novak c7448c03fb Added FREERDP_LOCAL 
CMake 2.8 does not support default visibility on windows.
To allow building tests add the FREERDP_LOCAL define for each
function that is internal to FreeRDP.
When build with testing these functions are exported and available
for use by tests.
