+  * On some systems, Int is not the same size as CInt.
+  
+  - Added hidden module Sound.PortMidi.DeviceInfo, moving DeviceInfo and peekDeviceInfo there
+   - this allowed it to be a hsc2hs module, enabling peekDeviceInfo to use C generated structure offsets and sizes
+  - FFI declarations for C calls that take and return PmError and PmDeviceID have been changed to take and return CInt rather than Int
+  - Haskell functions interfacing with C calls have had fromIntegral calls added as needed
+  - toPMError convenience function added, which replaced many calls to toEnum
+  - FFI declaration for Pm_CountDevices added, countDevices became a Haskell function
+  - PMError's toEnum function produces a more useful error message when the "impossible" happens
