Homebrew gcc builds starting with 12.4.0, 13.3.0 and 14.1.0 enabled the `availability` attribute. This broke builds because the way the Apple SDK uses attributes (when available) are incompatible with how gcc accepts them. Causing these errors: ``` error: attributes should be specified before the declarator in a function definition error: expected ',' or '}' before ``` Upstream commits implementing the `availability` macro: gcc-12:fd5530b7cbgcc-13:cb7e4eca68gcc-14:ff62a10886The project above is a Darwin gcc compatibility pack, that is applied to Homebrew gcc builds. This patch works by redefining the `availability` macro to an invalid value, making `__has_attribute(availability)` checks fail, stopping Apple SDK from inserting the incompatible attributes. It also replaces the previous, local workaround for `lib/macos.c`. Example with gcc 12.4.0 with macOS SDK 14.0 (Xcode 15.0.1): ``` In file included from <path-to-sdk>/MacOSX14.0.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CoreFoundation.h:54, from <path-to-sdk>/MacOSX14.0.sdk/System/Library/Frameworks/SystemConfiguration.framework/Headers/SCDynamicStoreCopySpecific.h:30, from /Users/runner/work/curl/curl/lib/macos.c:33, from /Users/runner/work/curl/curl/build/lib/CMakeFiles/libcurl_shared.dir/Unity/unity_0_c.c:244: <path-to-sdk>/MacOSX14.0.sdk/System/Library/Frameworks/CoreFoundation.framework/Headers/CFUserNotification.h:126:1: error: attributes should be specified before the declarator in a function definition 126 | CF_INLINE CFOptionFlags CFUserNotificationCheckBoxChecked(CFIndex i) API_AVAILABLE(macos(10.0)) API_UNAVAILABLE(ios, watchos, tvos) {return ((CFOptionFlags)(1UL << (8 + i)));} | ^~~~~~~~~ ``` Ref: https://github.com/curl/curl/actions/runs/9787982387/job/27025351601?pr=14096#step:7:18 The gcc vs. llvm/clang incompatibility possibly tracked here upstream: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108796 More info: https://github.com/llvm/llvm-project/issues/817678433baadechttps://discourse.llvm.org/t/changing-attribute-ast-printing-location-for-gcc-compatibility/73215 https://reviews.llvm.org/D159362 Follow-up todb135f8d72#14119 Ref: https://github.com/curl/curl/pull/14091#issuecomment-2222703468 Fixes #13700 Cherry-picked from #14097 Closes #14155
