@AaronBallman If you try to compile the following program after this patch
```
void free ();
typedef enum {REG_EESCAPE} reg_errcode_t;
typedef struct {int *stack;} compile_stack_type;
reg_errcode_t byte_regex_compile () {
compile_stack_type compile_stack;
return (free (compile_stack.stack), REG_EESCAPE);
}
```
cmd: `clang -Wimplicit-int-enum-cast -c pre.i`
It will give an incorrect diagnostic:
```
pre.i:6:37: warning: implicit conversion from 'int' to enumeration type
'reg_errcode_t' is invalid in C++ [-Wimplicit-int-enum-cast]
6 | return (free (compile_stack.stack), REG_EESCAPE);
| ~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
1 warning generated.
