Hi Guys,

  I would like permission to apply the patch below.  It is a revised
  and simplified version of the patch submitted here:

http://gcc.gnu.org/ml/gcc-patches/2004-05/msg00860.html

  The patch adds a new C++ specific target macro which is used in the
  import_export_class() function to allow backends to overrule the
  decision about whether a class should be imported or exported.  This
  is needed for the Symbian OS which has complicated rules about
  exporting classes depending upon the attributes that have been set
  on them or their ancestors.

  The bulk of the original patch has now been moved into the SH
  backend and will be contributed if this patch is approved.

Let's just have it return a value. Fine with that change.
