Microsoft's and Sun's compilers would be more likely to run into issues,
particularly Sun's; Sun has had a policy of preferring solid backward
compatibility to standards compliance, so I've tended to have more
problems getting correct, standard C++ to run on their compiler than on
others.  This is particularly true of template-based code and nested
classes.
