Hi Lars,

Hmmm I see what's going on.

The .eln file is produced by 'gcc_jit_context_compile_to_file', we could
just produce the temporary .elc before calling it and renaming it
afterwards but unfortunatelly 'gcc_jit_context_compile_to_file' takes a
considerable part of the compilation time, as a consequence we'd go back
to the reason this bug was opened for.

I think the best solution is to touch the .eln file once the final .elc
is produced.

I'll put a patch together.

  Andrea
