compilation failure with gcc-13

Compilation with gcc-13 doens't work. I get this error:

Does anybody have any idea about this ?

Thanks in advance for your help.

I am pretty sure that's just a missing include. I added that include in PR #1958 (plus a bunch more for good measure).

This patch indeed solve the problem.
