D compilers can compile multiple modules in one call. Common imports have to be processed only once, speeding up the build significantly.

For this to work with separate build-dirs, the options -od<objdir> and -op have to be considered.

Here is an example call:

dmd -oqobj -op -c src/mod1.d src/pak1/mod2.d src/pak2/mod3.d

will generate:

obj/mod1.o
obj/pak1.mod2.o
obj/pak2.mod3.o

Bug party triage: Needs batch processing from issue 1086.

Adjust triage of issues.

Batch build support has now been added, so this should be relatively straightforward to do for DMD, too. Patch welcome. See Tool/msvc.py for the best real-world example of how it can be used.
