/*

Problem related to the direct comparison of strings
in the file allocate.cxx (line 55)

          ......
	  String *local_decl = Getattr(dn,"decl");
	  if (local_decl && !Strcmp(local_decl, base_decl)) {
          ......

with the direct string comparison, no equivalent types
are checked and the two 'write' functions appear to be
different because

  "q(const).f(r.bss::PersEngine)." != "q(const).f(r.bss::Engine)."
