Building with clang on Debian 12 (bookworm; clang 14) and Debian 13 (trixie; clang 19) will result in a warning about the
nonstringattribute not being valid. You need newer clang 21+ for this to work.This PR adds a check to determine the version of clang and use/suppress the use of the attribute depending version found.
