[Issue 23143] New: ImportC: forward enum declarations result in uninformative errors

[d-bugmail--- via Digitalmars-d-bugs]

https://issues.dlang.org/show_bug.cgi?id=23143

  Issue ID: 23143
   Summary: ImportC: forward enum declarations result in
uninformative errors
   Product: D
   Version: D2
  Hardware: x86
OS: Windows
Status: NEW
  Keywords: ImportC
  Severity: enhancement
  Priority: P1
 Component: dmd
  Assignee: nob...@puremagic.com
  Reporter: maxsamu...@gmail.com

Test case 1:

enum _POOL_TYPE;

enum _POOL_TYPE {
NonPagedPool,
NonPagedPoolExecute = NonPagedPool
};

Error: `enum _POOL_TYPE` has no members


Test case 2:

typedef enum _POOL_TYPE POOL_TYPE;

enum _POOL_TYPE {
NonPagedPool,
NonPagedPoolExecute = NonPagedPool
};

Error: undefined identifier `NonPagedPool`

Forward enum declarations are forbidden by C11. However, they are used in
Windows SDK headers, and there are no workarounds that wouldn't involve
additional preprocessing.

  The expression (or rather it's context is still worthy of being illegal)
