IMHO this is the expected behaviour since the compiler comes 
before the linker and `pragma(lib)` is a linker directive, so if 
dimedll.di is not present it looks for dimedll.d instead and just 
compiles the code.

The link to DLL is only present in the actual lib-file and only 
used by the linker.

The pitfall with DMD is that the automatic generated di-file is 
not usable as it contains a mixin that is meant for the DLL but 
not the application that links it, resulting in _ModuleInfoZ 
error while trying.
