We need GCC and clang versions because of compiler and header file conflicts. While it is quite possible to #include Apple's CoreServices.h when compiling C source code with clang, trying to build it with GCC currently fails with this error: In file included from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Security.framework/Headers/AuthSession.h:32, from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Security.framework/Headers/Security.h:42, from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/CoreServices.framework/Frameworks/OSServices.framework/Headers/CSIdentity.h:43, from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/CoreServices.framework/Frameworks/OSServices.framework/Headers/OSServices.h:29, from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Headers/IconsCore.h:23, from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Headers/LaunchServices.h:23, from /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/CoreServices.framework/Headers/CoreServices.h:45, /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/System/Library/Frameworks/Security.framework/Headers/Authorization.h:193:7: error: variably modified 'bytes' at file scope 193 | char bytes[kAuthorizationExternalFormLength]; | ^~~~~ The underlying reason is that GCC (rightfully) objects that an `enum` value such as `kAuthorizationExternalFormLength` is not a constant (because it is not, the preprocessor has no knowledge of it, only the actual C compiler does) and can therefore not be used to define the size of a C array. This is a known problem and tracked in GCC's bug tracker: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93082 In the meantime, let's not block things and go the slightly ugly route of declaring/defining the FSEvents constants, data structures and functions that we need, so that we can avoid above-mentioned issue. Let's do this _only_ for GCC, though, so that the CI/PR builds (which build both with clang and with GCC) can guarantee that we _are_ using the correct data types.
