It is not the bug. This is a new feature required for showing of 
UnitName. Previosly this info was also available using TypeInfo() 
routine only compiler wrote nil pointer for the ClassInfo. Now it writes 
correct pointer.

This is delphi 2010 compatible behavior. Only info about published 
methods is not written for classes with {$M-}.
