Some GNU C version guards implicitly include the clang compiler, because clang reports itself as GCC 4.2.1. This implicit inclusion doesn't happen if the guard requires a GCC version above 4.2.1. Fix two such guards to explicitly include clang where it does support the guarded feature: - curl/curl.h: use `typecheck-gcc.h` with clang. llvm clang v14+ supports this. The corresponding Apple clang version is also v14. Ref: https://en.wikipedia.org/wiki/Xcode#Toolchain_versions Apple clang v14 tested OK in CI: https://github.com/curl/curl/actions/runs/16353901480/job/46207437204 - tool_urlglib: use `__builtin_mul_overflow()` with clang v8+. llvm clang v3.8+ supports this, but to accommodate for Apple clang, start with v8, the Apple version having the mainline v3.8 feature set. Also fix compile warnings triggered by the above: - lib1912: fix duplicate `;`: ``` tests/libtest/lib1912.c:44:57: error: empty expression statement has no effect; remove unnecessary ';' to silence this warning [-Werror,-Wextra-semi-stmt] 44 | print_err(o->name, "CURLOT_LONG or CURLOT_VALUES"); | ^ [...] ``` Ref: https://github.com/curl/curl/actions/runs/16351302841/job/46198524880?pr=17955#step:12:61 - lib2032: silence typcheck warning with a cast: ``` tests/libtest/lib2032.c:145:29: error: sizeof on pointer operation will return size of 'CURL **' (aka 'void **') instead of 'CURL *[3]' (aka 'void *[3]') [-Werror,-Wsizeof-array-decay] 145 | ntlm_easy + num_handles); | ~~~~~~~~~ ^ ``` Ref: https://github.com/curl/curl/actions/runs/16351302841/job/46198524880?pr=17955#step:12:86 Closes #17955 |
