I tried building Python 1.6a2 using SGI's cc (7.3) and readline 4.1, and
also on a NeXT 3.3 using gcc 2.95.2. There is no problem with control-C on
either platform, so the problem appears to be related to gcc 2.95.2 on
SGI, and shouldn't be too hard to track down now that I can compare
debugging traces for working and broken versions.  Since the one known
area where gcc fails _reliably_ on Irix is padding in small structures, 
I will snoop around a bit in the readline sources and examples to see if
I can construct a smaller example of the problem.
