printf() has a different syntax to Go #94

There are some symbols in C's printf, like %ld that are not supported in Go. It results in Go printing something like %!!(MISSING).

There should be a noarch.Printf(), but only used when the first argument cannot be determined to not include these syntax to improve performance when most of the time it is a string literal.

Maybe it's possible to transpile MUSL's printf implementation and use that as noarch.Printf?

You can use that code as protitype. https://github.com/Konstantin8105/c4go/blob/bb2ab78fe0fb931f5fc42afee3501b7b02742148/transpiler/literals.go#L35-L52 And use like that: https://github.com/Konstantin8105/c4go/blob/bb2ab78fe0fb931f5fc42afee3501b7b02742148/transpiler/literals.go#L58
