[llvm] r185627 - Supporting ssize_t on WIN64 with its proper size. Patch thanks to David Cournapeau!

[David Majnemer]

Unless I am mistaken, this commit has the DataTypes.h.cmake file using int for 32 bit Windows while the DataTypes.h.in file used long. For consistency, we should use long to match what msdn specifies.
