It depends. . . if the compiled program is 100% compiler output, then it's fine. If the compiled program ends up including bits of library code that ships with the compiler, then, in the absence of special exceptions, the output will also need to be AGPL-licensed. That's exactly why, for example, LLVM ships with a modified version of the Apache license: http://llvm.org/foundation/relicensing/LICENSE.txt http://llvm.org/foundation/relicensing/LICENSE.txt (see the bottom)
