[Insight-developers] Is it ITK or gcc that's broken?

[Paul Hughett]

I just upgraded my Linux installation to RedHat 7.1; I *think* that the
gcc version that it actually uses is the gcc 2.95.2 that I've been using
for the past six months rather than the new broken gcc 2.96 that comes with
RH 7.1.  Nevertheless, when I updated from the repository, configured, and
made, I got the following errors almost immediately.  

Is the code in the repository broken, or should I be looking for errors
in the new RedHat version?  For what it's worth, another package that I
am working on compiles without a hiccup.
