          Issue ID: 22876
           Summary: importC: ambiguous cast affects expression parsing
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

          Reporter: duser at neet.fi

two examples, i think they're the same bug

// test1.c
int printf(char *, ...);
int main()
{
        int a = 0;
        // dmd gives 1, other compilers -1
        // bug disappears if the parentheses around (a) are removed
        int b = - (a) - 1;
        printf("%d\n", b);
}

// test2.c
int example2()
{
        int *a, *b;
        // Error: incompatible types for `(a) - (cast(char*)b)`: `int*` and
`char*`
        // works if the parentheses around (a) are removed
        long diff = (char*)(a) - (char*)b;
}
