Add chibicc This program popped up on Hacker News recently. It's the only modern compiler I've ever seen that doesn't have dependencies and is easily modified. So I added all of the missing GNU extensions I like to use which means it might be possible soon to build on non-Linux and have third party not vendor gcc binaries. 2020-12-05 20:20:41 +00:00			`void __assert_fail(const char , const char , int) hidden wontreturn relegated;`
