PATCH for g++: internal compiler error

[Mark Mitchell <mmitchell at usa dot net>]

Jason --
  
  Here's a patch that avoids aborting on code like:

// Build don't link:

class A
{
  template<class T>T epsilon; // ERROR
};

  May I check this in, with corresponding test case?  (A peculiarity
of my current location prevents me from creating diffs for new test
cases, so I can't show that; it would be the code above.)
