When building a language, the editor becomes inactive (turning grey) and should become activated again when the build is done. However, in the current nightly it stays inactive.

This is caused by a wrong order of operations in the language build. generate-pp is called after sdf2imp.eclipse.load, which makes reloading fail because the language has not been completely built yet. The fix is to move generate-pp before the pppack target, and making it depend on sdf2imp.
