Are you sure?  According to this page, it seems that this declaration
should not be necessary:

  http://msdn.microsoft.com/en-us/library/zkwh89ks%28v=vs.80%29.aspx

  __cdecl
  [...]
  This is the default calling convention for C and C++ programs.
  [...]
  Because the C naming and calling conventions are the default, the
  only time you need to use __cdecl is when you have specified the /Gz
  (stdcall) or /Gr (fastcall) compiler option.

The alternative way of phrasing the above is that you need "__cdecl" there just in case the code is compiled with /Gz or /Gr.
