             Bug #: 57133
           Summary: false const qualifier warning typedef
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: grpintar@gmail.com


typedef char *type;

void f(const type t)
{

}

int main(void)
{
    const char *str = "string";
    f(str);
    return 0;
}

warning: passing argument 1 of 'f' discards 'const' qualifier from pointer
target type [enabled by default]
  f(str);
  ^
note: expected 'type' but argument is of type 'const char *'
 void f(const type t)
      ^

It is similar with gcc 4.5.3.
