New Version does not compile AdvMemo.hpp error

When recompiling a program after updating to in codegear Rio and CodeGear Sydney it does not compile with an error in AdvMemo.hpp (line 1921)
[bcc32 Error] AdvMemo.hpp(1921): Declaration terminated incorrectly
and the line with error is:

virtual System::UnicodeString __fastcall LineBreak();

The problem seems to be in the word "LineBreak" because if I change a letter "LineBrea" for example, then it compiles well.
Any idea?

Does this happen in a new application?
Or is this in an application that uses other 3rd party HPP files with which there is perhaps a conflict?
If so, try reordering the HPP files first.
