Dolphin SVN r4638, r4630- linux compile error

[benpicco]

When I try to build revision 4630 on x86_64 Linux, I get

Code:

Compiling shared Build/Linux-x86_64-release/Source/Plugins/Plugin_Wiimote/Src/FillReport.os
Source/Plugins/Plugin_Wiimote/Src/FillReport.cpp: In function 'int WiiMoteEmu::GetMapKeyState(int)':
Source/Plugins/Plugin_Wiimote/Src/FillReport.cpp:305: error: 'GetAsyncKeyState' was not declared in this scope
scons: *** [Build/Linux-x86_64-release/Source/Plugins/Plugin_Wiimote/Src/FillReport.os] Error 1
scons: building terminated because of errors.

GetAsyncKeyState looks like a WindowsAPI function to me
