Sized enums still aren't supported

[cD1rtX3]

Type: Bug

Step 0: Set your "C Standard" to at least c23 (I have it on gnu23).

Step 1: Declare a sized enum:

enum: uint32_t {
    foo = 0xDEADBEEF,
    bar = 0x12345678,
    baz
}

Step 2: Distinct lack of profit.

Even with #7471 being closed, I still have this issue with Intellisense, though the code compiles fine.

@cD1rtX3 This is not implemented by our our parser yet -- you can track the progress in the EDG column at https://en.cppreference.com/w/c/compiler_support/23 row "Enumerations with fixed underlying types".

The root c23 issue is at #10696, but we can use this issue to track this specific feature.

[jleveque]

@sean-mcmanus: According to the progress spreadsheet (row 193), this feature was recently added to EDG as of release 6.8. Can you please provide an ETA as to when this will make its way into vscode-cpptools?

[sean-mcmanus]

@jleveque Yeah, we plan to add that when it's available and integrated into our code -- I don't have any insider knowledge on this but I'm guessing 6.8 might not be done yet and the progress is just showing what is pending and they have more stuff to add and test before releasing it? So I don't have an ETA yet.
