c++: Allow exporting a typedef redeclaration [PR102341]
A typedef doesn't create a new entity, and thus should be allowed to be
exported even if it has been previously declared un-exported. See the
example in [module.interface] p6:
export module M;
struct S { int n; };
typedef S S;
export typedef S S; // OK, does not redeclare an entity
PR c++/102341
gcc/cp/ChangeLog:
* decl.cc (duplicate_decls): Allow exporting a redeclaration of
a typedef.
gcc/testsuite/ChangeLog:
* g++.dg/modules/export-1.C: Adjust test.
* g++.dg/modules/export-2_a.C: New test.
* g++.dg/modules/export-2_b.C: New test.
