I don't have rights to formally approve this GCC/Rust change, but I'll
note that it follows "as obvious" (see
<https://gcc.gnu.org/gitwrite.html#policies>, "Obvious fixes") to the
corresponding GCC/Go change, which has been approved:
<https://inbox.sourceware.org/CAKOQZ8wDWc7G5_jBNK1jvgChhiURceeAmZb5Bqrx_VZjeJP2Vw@mail.gmail.com>,
and which is where this GCC/Rust code has been copied from, so I suggest
you push both patches at once.


Grüße
 Thomas
