This is a modern statically-linked GNU C2X toolchain.
You have the freedom to obtain the original sources to these binaries,
and build ones just like them, by visiting:
https://www.gnu.org/
https://github.com/richfelker/musl-cross-make
The musl-cross-make tool also produces libraries and header files. We've
only vendored the statically-linked executable files, since Cosmopolitan
won't depend on GPL-licensed headers / runtime libraries.
We haven't made any modifications to the original software. The versions
we chose are documented in $PKG/LICENSE.txt. Here's our Musl
build config for maximum transparency:
commit 38e52db8358c043ae82b346a2e6e66bc86a53bc1
Author: Rich Felker <dalias@aerifal.cx>
Date: Wed Dec 18 14:29:07 2019 -0500
switch linux kernel headers to 4.19.88 by default
using slim headers-only version. this change is needed to support all
future versions of musl on 32-bit archs, since prior to 4.16 the
kernel headers had incompatibility with userspace time_t not matching
the kernel's old (32-bit) time_t. support for older headers will be
dropped entirely soon.
