I cannot answer the question to Paul ...

I still do not fully like the handling of CLASS, but I think the patch
is still an improvement and thus OK for check in.

Nit: You miss a space after CLASS_DATA, e.g.

+      allocatable = CLASS_DATA(sym)->attr.allocatable;
should be
+      allocatable = CLASS_DATA (sym)->attr.allocatable;

The only exception is #define where no space is OK.
