Tar Gzipped code

Tar gzipped file is attached. To reproduce the bug, untar and compile foo.d.
Note that when all files/modules are compiled together, the compiler does not
give any error.

This is what I get:

$ dmd -c foo.d
fred.d(4): Error: function void fred.qux!(bar).qux.thunk() does not override
any function, did you mean to override void foo.foo.thunk()?
fred.d(7): Error: template instance `fred.qux!(bar)` error instantiating
