Bug ID: 118374
Summary: Missing fixit for underlying enum type
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Blocks: 118371
Target Milestone: ---
This is from https://bugs.gentoo.org/938230.
```
enum Flags : uint8_t {};
```
We emit:
```
<source>:1:12: error: found ':' in nested-name-specifier, expected '::'
1 | enum Flags : uint8_t {};
| ^
| ::
<source>:1:6: error: 'Flags' has not been declared
1 | enum Flags : uint8_t {};
| ^~~~~
<source>:1:22: error: expected unqualified-id before '{' token
1 | enum Flags : uint8_t {};
| ^
Compiler returned: 1
```
.. which is confusing for folks if uint8_t used to come in via a header.
Upstreams don't usually struggle with this but sometimes packagers do who
haven't seen it before.
