AFAIK this was discussed here already along with solution that does not
require renaming.

In the latest version in sandbox_jakacki_frontend1 (to be merged to MAIN
soon) each class has its own file, so class TypeInfo has its file
TypeInfo.h; we cannot rename this file without breaking a rule, that the
file name is constructed from class name. We cannot rename class without
breaking backward compatibility. So that's why I don't like renaming.

This will break if you are building new version of OpenC++, but have the
old one installed in directory, that is early in include path (e.g. if you
installed in /usr/local), as this directive will pull in the old header.
Also remember about issues when building with srcdir!=builddir (I am not
sure if they hit here, I have no time to analyze it at the moment, sorry.)
The solution I used in sandbox_jakacki_frontend1 is:

#include "../opencxx/typeinfo.h"
