DMD does require the sources, or at least the sources you'd like to have
inlined. GCC requires all the sources used to be compiled with a special switch:
"When using multiple steps, it is strongly recommended to use exactly the same
optimization and machine-dependent options in all commands, because conflicting
options during compilation and link-time may lead to strange errors."
