Bug 19462

Since I don't think the people at gcc-bugs.org support Red Hat's
gcc 2.96-54, and because I've made more good than bad experience with that
particular snapshot, I post this here...

The following code fails to compile. Apparently,  without any reason.

  http://sourceforge.net/projects/sidplay2/

The code fragment in question is this:

void sidplayer_pr::evalBankSelect (ubyte_sidt data)
{   // Determine new memory configuration.
    isBasic  = ((data & 3) == 3);
    isIO     = ((data & 7) >  4);
    isKernal = ((data & 2) != 0);   // *** this is line 583, isKernal is
bool
    _bankReg = data;
#ifdef DEBUG
    ram[1]   = data;
#endif // DEBUG
}
