I got the following warning when compiling zig-wasm2c:

C:\git\zig\stage1\wasm.h(55) : warning C4715: 'WasmMut_toC': not all control paths return a value

This is because the C compiler doesn't understand that the panic function from panic.h is noreturn. I copied some code from zig.h that tries to define a noreturn attribute based on preprocessor macros and included that in panic.h. No more warning.
