Currently the man man page doesn't mention any header to include for 'environ':
> NAME
>      environ — user environment
>
> SYNOPSIS
>      extern char **environ;

Shouldn't there be a header where it is declared?

No, it "must be declared by the user if it is to be used directly," according to https://pubs.opengroup.org/onlinepubs/9699919799/functions/environ.html.  Perhaps the man page should make that more clear.
