These files are verbatim copies from the current (2.95.2) gcc source code
without further modification. They must match the gcc version
that checkergcc will be built for.

Only the file tinfo2.cc has a small patch - see __CHECKER__.
Hopefully this will go into the main tree so that we can use 
completely unpatched gcc sources in the future.
