I'm probably mistaken by the code I read. I'm having a hard time reading it 
honestly.

I'm not adding anything but moving the RISC-V support to a really old GCC that 
we can compile with MesCC. MesCC is proven to work in older tcc versions but 
not in the most recent one so all our infrastructure is set up to work on that 
old TinyCC.

If you want to know more, you can take a look to:

I have not other chance at the moment but make this backport, as well as I 
already did with GCC.

Maybe this makes some more sense to you now you know.

Could you please help me understand how this internals work?

Thank you very much,
Ekaitz
