[Bug c++/39371] [4.2/4.3/4.4 Regression] Incorrectly rejects switch((unsigned int)boolvar)

[jakub at gcc dot gnu dot org]

This isn't related to just bool, e.g.:
void
foo (unsigned char b)
{
  switch ((unsigned int) b)
    {
    case 1:
    case 257:
      break;
    }
}
also results in
pr39371-2.C:7: warning: large integer implicitly truncated to unsigned type
pr39371-2.C:7: error: duplicate case value
pr39371-2.C:6: error: previously used here

In C both testcases are fine.
