## Message

```
improvements to zig's implementation of libc and WebAssembly

 * rename std/special/builtin.zig to std/special/c.zig
   not to be confused with @import("builtin") which is entirely
   different, this is zig's multi-target libc implementation.
 * WebAssembly: build-exe is for executables which have a main().
   build-lib is for building libraries of functions to use from,
   for example, a web browser environment.
   - for now pass --export-all for libraries when there are any
     C objects because we have no way to detect the list of exports
     when compiling C code.
   - stop passing --no-entry for executables. if you want --no-entry
     then use build-lib.
 * make the "musl" ABI the default ABI for wasm32-freestanding.
 * zig provides libc for wasm32-freestanding-musl.

```
