Forward Reference -g bug (minor) code reduction challange

[clayasaurus]

Hi, I have code that will compile with

dmd -c def.d

but will give forward reference errors when compiled with

dmd -c -g def.d

I have not been able to reduce the code, maybe someone with more 
understanding can.

The offending code can be found here -->

big to upload to digitalmars server.)
