The compiler itself is under the GPLv2+; the support code that gets built into user programs is under the LGPLv2+. This matches the existing practice for the KRoC project. (As with Occade, I've used the new GPLv3-style license header in the source files, though, since that avoids having to update the FSF's postal address.)
