/*
  On MSWindows platforms, one of these defines must always be set when
  building application programs:

   - "COIN_DLL", when the application programmer is using the library
     in the form of a dynamic link library (DLL)

   - "COIN_NOT_DLL", when the application programmer is using the
     library in the form of a static object library (LIB)

  Note that either COIN_DLL or COIN_NOT_DLL _must_ be defined by the
  application programmer on MSWindows platforms, or else the #error
  statement will hit. Set up one or the other of these two defines in
  your compiler environment according to how the library was built --
  as a DLL (use "COIN_DLL") or as a LIB (use "COIN_NOT_DLL").

  (Setting up defines for the compiler is typically done by either
  adding something like "/DCOIN_DLL" to the compiler's argument line
  (for command-line build processes), or by adding the define to the
  list of preprocessor symbols in your IDE GUI (in the MSVC IDE, this
  is done from the "Project"->"Settings" menu, choose the "C/C++" tab,
  then "Preprocessor" from the dropdown box and add the appropriate
  define)).

  It is extremely important that the application programmer uses the
  correct define, as using "COIN_NOT_DLL" when "COIN_DLL" is correct
  will cause mysterious crashes.
