Header file generation not working correctly

[Pablo Delado]

I am using the d compiler on macosx and when I attempt to 
generate header files the d compiler simply copies the contents 
of my d files into the di files instead of generating 
declarations.

Command that I execute is:   dmd -Hd./ -Hftest.di -lib test.d
After speaking with others in the irc I was told that the command 
was correct and that I should have generated the required 
declarations.
