28  * Starting with PSAPI version 2 for Windows 7 and Windows Server 2008 R2, this function is defined as K32GetProcessMemoryInfo in Psapi.h and exported
29  * in Kernel32.lib and Kernel32.dll. However, you should always call this function as GetProcessMemoryInfo. To ensure correct resolution of symbols
30  * for programs that will run on earlier versions of Windows, add Psapi.lib to the TARGETLIBS macro and compile the program with PSAPI_VERSION=1.
31  *
32  * We do this before anything to make sure it's done.
