           Summary: [clang on Wine]: constant integer size rejected as not
                    being constant
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: kremenek at apple.com
                CC: llvmbugs at cs.uiuc.edu


The following self-contained code example (reduced from a case in Wine) is
rejected by Clang because the size of the array is deemed not a constant:

typedef unsigned long UINT_PTR, *PUINT_PTR;
typedef struct HHOOK__ {} *HKEY;
static HKEY special_root_keys[((UINT_PTR)((HKEY) 0x80000006) -
(UINT_PTR)((HKEY) 0x80000000) + 1)];

The error emitted by clang:

t.c:3:13: error: variable length array declaration not allowed at file scope
static HKEY special_root_keys[((UINT_PTR)((HKEY) 0x80000006) -
(UINT_PTR)((HKEY) 0x80000000) + 1)];
            ^
