Running dub run with --verbose indicates that dub is actually 
running both the "dmd -g -c -betterC source/app.d -ofd_betterc.o" 
and the "dmd -ofd_betterc d_betterc.o -g" commands. Note that the 
second dmd call doesn't include the -betterC flag. Running the 
second dmd command manually with the -betterC flag does give the 
expected undefined reference errors.
