Sorry for putting you in the To field, I'll use Cc in the future.

I agree that the commit message is a little short, and I will iterate on
that. Furthermore, I agree that gcc compatibility would allow to parse
this statement. However, the given sequence is not unique, and the gcc
documentation states that the semicolon is mandatory.

https://gcc.gnu.org/onlinedocs/gcc/Label-Attributes.html

I'll add more details to the commit message.

Best,
Norbert
