Ugly, but this something that is near and dear to all code that needs
run under Windows of any flavor.

Windows targeted code needs the following to be equivalent

     void __attribute__ ((dllexport)) f();
     __attribute__ ((dllexport)) void f();

GCC already handles the following:

     void f() __attribute__ ((dllexport));

but that's not in common use in that world.

The C++ front-end has had historical problem in handling these ugly but
much needed constructs, and a source of regressions among major releases.
