devel/bazel5: fix build with clang 19
Clang 19 has become more strict about C23 extensions, which results in errors building devel/bazel5: external/upb/upb/upb.c:215:25: error: defining a type within '__builtin_offsetof' is a C23 extension [-Werror,-Wc23-extensions] 215 | n = UPB_ALIGN_DOWN(n, UPB_ALIGN_OF(upb_arena)); | ^~~~~~~~~~~~~~~~~~~~~~~ external/upb/upb/port_def.inc:94:38: note: expanded from macro 'UPB_ALIGN_OF' 94 | #define UPB_ALIGN_OF(type) offsetof (struct { char c; type member; }, member) | ^~~~~~ /usr/include/stddef.h:64:42: note: expanded from macro 'offsetof' 64 | #define offsetof(type, field) __offsetof(type, field) | ^~~~ /usr/include/sys/cdefs.h:324:53: note: expanded from macro '__offsetof' 324 | #define __offsetof(type, field) __builtin_offsetof(type, field) | ^~~~ external/upb/upb/port_def.inc:92:48: note: expanded from macro 'UPB_ALIGN_DOWN' 92 | #define UPB_ALIGN_DOWN(size, align) ((size) / (align) * (align)) | ^~~~~ To work around this, amend extra-patch-upb_bazel_build__defs.bzl to also add -Wno-c23-extensions. Alternatively, the -Werror option could be taken out. PR: 282166 Approved by: vishwin (maintainer) MFH: 2024Q4 (cherry picked from commit a34c378a051d3df7767855bb37fc359924f4dcc1)
