I don't want that kind of symbol just floating around waiting to be abused. It appears when you use something like Integer'Image(123) gnat assumes you have a memcpy symbol to call, quite pesty.

Indeed about 600K, this is mostly dlopen and other shit. GNAT by default uses GNU's libc init and exit functions. And those functions seem to want all the others, I've done a little work in removing calls and rebuilding glibc, but so far no luck. As far as MUSL libc goes, this is probably 10 / 20K or so, it is used for init and putchar etc. (and yes gnat will use memset, memcopy for aggregate statements, others => 0) I agree, GNU libc is only overhead.

There's not much point in this exercise if it's still in there, obscenely taking up 800+kB. For what does GNAT even use libc ? for memcpy?! Libc gotta go.
