WIP: Add a C Library, let's try to compile a Hosted GCC cross-compiler using this! 2022-10-01 18:59:22 +00:00			`#include <stdlib.h>`

libc: Change bits/macros.h to use a __lc_ prefix for internal macros That way, we don't pollute user programs with our own 'noreturn' and 'deprecated' macros 2022-10-15 07:52:37 +00:00			`__lc_noreturn void abort()`
