Comment (by frederic.bron@…):

 This is easy to to fix. integral_c is defined by:
 template< typename T, T N > struct integral_c;

 So the 2nd template parameter is of type T=UnsignedIntegralChannel.

 Therefore, -1 can easily be replaced by either
 std::numeric_limits<UnsignedIntegralChannel>::max() or
 static_cast<UnsignedIntegralChannel>(-1)

 See patch attached.
