clang supports this as an extension in C:
$ clang -Weverything enum.c
warning: include location '/usr/local/include' is unsafe for cross-compilation
[-Wpoison-system-directories]
enum.c:1:6: warning: enumeration types with a fixed underlying type are a Clang
extension [-Wfixed-enum-extension]
enum : int { a }; int main(void) { return 0; }
^~~~~
2 warnings generated.
vs. with gcc:
$ /usr/local/bin/gcc enum.c
enum.c:1:6: error: expected '{' before ':' token
1 | enum : int { a }; int main(void) { return 0; }
| ^
