You need LLVM to compile Stylo, Mozilla's new rendering engine based on Rust. Currently no on on the project knows how to handle that (on Windows), so we all have ac_add_options --disable-stylo unset LLVM_CONFIG in our .mozconfig files. It would be nice if our build/release engineer could advise us further. Jörg.

I still had some error messages, and after fighting for a while and googling I figured out that I was running into Bug 1383578 <https://bugzilla.mozilla.org/show_bug.cgi?id=1383578>. After removing the quotes from line 42 of start-shell.bat in the Mozilla Build 3.0 package, my build completed successfully. Perhaps this might be helpful to anyone else who does a build on Windows for the first time.

I'm a lazy person still on Mozilla Build 2.x. So that information will come in handy later. Jörg.
