//
// Test for conversions that were supposed to be explicit operator
// conversions on UIntPtr and IntPtr, but due to historical reasons
// ended up in the CSC compiler.
//
// See bug http://bugzilla.ximian.com/show_bug.cgi?id=59800 for details
//
// The conversions are:
//   UIntPtr->SByte
//   UIntPtr->Int16
//   UIntPtr->Int32
//   IntPtr->UInt64
//   UInt64->IntPtr
//   SByte->UIntPtr
//   Int16->UIntPtr
//   Int32->UIntPtr
