I think Erik asked about the "main" for the compiler itself. Your
response is about the "main" for the compiled class.
To answer Eruk's question: The compiler command line is processed
multiple times. First it is processed by the gcc "driver" program,
which is builtr using gcc.c and java/jvspec.c. That then invokes
jc1, where it is processed in toplev.c, but it call various
helper routines.
