Excuse me for little offtopic. But the topic you are discussing I believe is important for many people who use U++.
Is there any possibility to include DMC builder into SVN version of TheIDE? Yes, I know that DMC is not compiling U++ itself, but TheIDE is good development platform to be used for many applications w/o U++.
I don't know if including a builder designed specially for a compiler that can't handle U++ is a good idea. On the other hand, including a generic build method that can handle DMC (and quite possibly other compilers), but with extra parameters that a user must provide and instructions on the site for setting up common compilers might be a good idea.
There is already "scipt builder", where you can use Esc to describe the build process.
