I did not play with llvm19 yet.

Checking the BPF CI netdev builds that went red yesterday 8pm PST leads to 
https://github.com/kernel-patches/bpf/actions/runs/10087416772

BPF selftests build is failing with:

    CC bench_local_storage_create.o 
3298 CC bench_htab_mem.o 
3299 CC bench_bpf_crypto.o 
3300 BINARY xskxceiver 
3301 <command-line>: error: "_GNU_SOURCE" redefined [-Werror] 
3302 <command-line>: note: this is the location of the previous definition 
3303 BINARY xdp_hw_metadata 
3304 BINARY xdp_features 
3305 TEST-OBJ [test_maps] htab_map_batch_ops.test.o 
3306 TEST-OBJ [test_maps] lpm_trie_map_batch_ops.test.o 
3307 TEST-OBJ [test_maps] sk_storage_map.test.o 
3308 TEST-OBJ [test_maps] map_percpu_stats.test.o

across all combos or architectures/compilers. I did not see anything related to LLVM19 though.

last failing build was today 5:17 am PST https://github.com/kernel-patches/bpf/actions/runs/10093925751
with the same symptoms.

First successful at 8:02am: https://github.com/kernel-patches/bpf/actions/runs/10096557745
