This modifies our wuffs dependency so that it no longer requires libc. This unblocks using wuffs from libghostty-vt on freestanding targets, which we'll eventually want for some Kitty graphics stuff.

// Minimal string.h so that wuffs can be translated and compiled without
|
|
// requiring libc headers (e.g. for wasm32-freestanding targets, or to
|
|
// avoid needing an Apple SDK for translate-c on macOS).
|
|
//
|
|
// Wuffs only calls the mem* family, whose symbols are provided by Zig's
|
|
// compiler-rt on targets without libc and by libc everywhere else. The
|
|
// declarations here match the standard C ABI, so this header is safe to
|
|
// use on every target, including ones that do link libc.
