  Well, surely if they're compiling for MSVC using -D_DLL in order to get the
DLL version of the runtime libs, when they compile under GCC they will also
want to get the DLL version of the runtime libs?  (Ideally their configure
scripts will define it or not according to --enable/disable-static/shared?)  I
don't quite see why it would be misuse to make the GCC toolchain respond to
-D_DLL in the same way as the MSVC one, and isn't that what would result in
this case?

  Likewise.
