One should say jhc code is really clear. It's the first compiler
code I try to read and for a moment I actually believed I could
write the patch :)

Below is my completely naive attempt. If you want to tell me
where to go from here, I'll try. (For instance: how do I get
'rt_bits_double_complex_' to exist.) However, I think this is far
beyond my skills...

Thanks for your thoughts,
