For the first warning there was a commit 3cb34fb0b0 "build: set toolchain macros from predefined macros" dated 2024-01-02 that was fixing similar issue. It is possible that documentation issues were fixed since bookworm-shipped version 22.11 as well. Depending on your goals you may try newer DPDK version, compiling libpcap with gcc and/or fewer warnings or just ignoring these warnings.
