Wait, wut? Do modules that get pulled in from dub's "importPaths" 
not get compiled in the same way?

The dstep-generated files were working for the most part -- 
standalone C functions had no problem -- it was only those 
structs that I was having problems with. But now that they're in 
the default /source folder, I don't get the linker errors 
anymore. <shrug>
