   1 /* These dllimport and dllexport appearing for a symbol.
   2    The desired behavior is that if both dllimport
   3    and dllexport appear (in either order) the result is dllexport.
   4
   5    Microsoft's MSVC 2.0 allows dllimport followed by dllexport for variables,
   6    but does not allow dllexport followed by dllimport.
   7
   8    In C, it's ok to redeclare a variable so this works for variables
   9    and functions.  In C++, it only works for functions.  */
