Ideally. Yes, but, as you said, it bring in some minor functions.

And how I can do this? silo is linked to libc, because it lacks a lot
of functions like str* and others... if I don't use libc, I had to
implement those functions on my own.

I'm not confident that I will able to do it :-)

I had already try that way, but silo lacks these functions:
str*
mem*
ext2*
udiv, umul, urem and probably others...

BTW, isn't __setjmp already defined also in libc5?
(I haven't a libc5 system here)

thanks
