Possibly uninitialized variable in include/bits/istream.tcc basic_istream::ignore

[Aaron W. LaFramboise]

I've been applying the patch below to fix an uninitialized variable 
warning causing mainline bootstrap to fail.  I have not analyzed the 
logic, so I have no idea what the correct fix is.  Perhaps the while 
loops needs to be changed to a do-while loop?
