I think you misunderstood me. `dub` is the D's build system and 
it "knows" how to call the D compilers, including gdc.

When you tell dub to build a static library (equivalent to "fat 
jar" for D) it will use whatever compiler options are needed to 
do so... you can run `dub build -v -release --compiler=gdc` to 
see which compiler options it's using to invoke gdc, and then you 
can just drop dub if you don't need it (though it's very useful 
to have).
