/* The following macros have to be defined, otherwise the autoload mechanism
   in autoload.cc leads to "multiple definition" errors.  The macros control
   the declarations of symbols in the Mingw64 w32api headers.  If they are
   not defined, a DECLSPEC_IMPORT will be added to the symbol declarations.
   This leads to a definition of the symbols in the sources using the
   autoloaded symbols, which in turn clashes with the definition in the
   w32api library exporting the symbols. */

   respect for the namespace and not undef'ed anymore, they tend to collide
   with otherwise innocent definitions in the application.  We check if they
   exist and if not, we undef them again after including the Windows headers. */
