I don't know exactly why the old dwt is significant smaller in code
size. Perhaps this is because Shawn combined many Java classes into
modules. I decided not to do this, instead I want to stay as close as
possible to the Java sources. So later merges are easier.
Another issue is, to have dynamic libs available. Afaik, at the moment
DMD doesn't support dynamic libs for classes/exceptions/GC on win32 nor
linux. On win32 DDL might be an option. But i don't know if libs would
solve your problem with the executable size.
So my main toolchain issues at the moment are:
- compile speed
- executable size
- dynamic lib supprt (D<->D with classes/interfaces/exceptions/...)
- distribution system with easy install and dependency management
- better debugging support and stacktrace information at runtime
