{ Some notes from as:
  1. DirectInput Enum callback functions which are documented with result
  type BOOL in the SDK had to be changed to result type integer because the debug
  version of DINPUT.DLL (which is the same for SDK versions 5.0, 5.2, 6.0, and 6.1)
  explicitely checks for two possible return values:
 
  0 - FALSE in C and in Delphi
  1 - TRUE in C, defined as DIENUM_CONTINUE
 
  In Delphi, TRUE means $FFFFFFFF (= -1) for the LongBool (= BOOL) data
  type, and AL = 1 (upper three bytes undefined) for the Boolean data type.
  The debug version of DINPUT.DLL will throw an external exception
  ("invalid return value for callback") when fed with either value.
 
  This change affects the following methods:
  EnumDevices, EnumObjects, EnumEffects, EnumCreatedEffectObjects
 
  2. Windows 98 and DX6 debug versions DInput and DSound
 
  Under Windows 98, the "debug" setup of the DirectX SDK 6.x skips DInput.DLL
  and DSound.DLL, i.e. makes you end up with the retail version of these two
  files without any notice.
  The debug versions of DInput.DLL and DSound.DLL can be found in the
  \extras\Win98\Win98Dbg folder of the SDK CD; they need to be installed
  "manually".
 
  This problem has been fixed with DX7 where the SDK installs the debug versions
  of DInput and DSound without any "manual" help.

  Windows 98 and debug versions DInput and DSound
 
  Under Windows 98, the "debug" setup of the DirectX SDK 6.x skips DInput.DLL
  and DSound.DLL, i.e. makes you end up with the retail version of these two
  files without any notice.
  The debug versions of DInput.DLL and DSound.DLL can be found in the
  \extras\Win98\Win98Dbg folder of the SDK CD; they need to be installed
  "manually".
