Please use the attached patch. It applies cleanly to both 9.1 and 9.0.
We don't need to consider 8.4, because ASLR became enabled by default in
Visual Studio 2008 and 8.4 doesn't support building with 2008.
I tested with Visual Studio 2008 Express. You can check if ASLR is disabled
using dumpbin. "dumpbin /headers <EXE_or_DLL_file>" outputs the following
lines. If the "Dynamic base" line is displayed, ASLR is enabled. If this
line disappears, ASLR is disabled.
8140 DLL characteristics
Dynamic base
NX compatible
Terminal Server Aware
