compile error with PDWORD_PTR

[trueClock.cxx]
typedef BOOL (WINAPI * PFNGETPROCESSAFFINITYMASK)(HANDLE, PDWORD_PTR, PDWORD_PTR);

Panda3D1.9_master/panda/src/express/trueClock.cxx:129:59: error: syntax error, unexpected IDENTIFIER
typedef BOOL (WINAPI * PFNGETPROCESSAFFINITYMASK)(HANDLE, PDWORD_PTR, PDWORD_PTR);

has PDWORD_PTR been redefined?
I changed PDWORD_PTR to DWORD_PTR*,and compile ok

vc2010 ,windows 7

Thanks, I forgot this in my commit yesterday. Checked in a fix.
