Subject: gcc12 warning suppression
Git-repo: git://sourceware.org/git/systemtap.git
Git-commit: 1549784e9c71e5bf80860d314e15e6019f899de4
References: bsc#1196583

The translator emits a pair of type declarations that alternate
between a char[] and a char*, depending on the size of strings
involved.  The polymorphic client code includes pointer null-checking,
which -Waddress code rejects for the char[] case.  The simplest
workaround is just to disable that particular diagnostic.
