Simon Kågström has released Cibyl 4, a free-as-in-speech (GPL) "programming environment that allows compiled C programs to execute on J2ME-capable phones. Cibyl uses GCC to compile the C programs to MIPS binaries, and these are then recompiled into Java bytecode. The programs are not parsed during runtime, and Cibyl is therefore well-performing. With Cibyl, games written in C can be ported to J2ME without switching language. The environment is tied to the GNU compiler tools (GCC and binutils) and only tested on Linux so far although it should work in other environments as well."
