-fborland-extensions on Linux

I want to port some C++ code that was originally written for Windows using Borland (Embarcadero C++ Builder10 Seattle) to Linux. The code makes extensive use of Borland’s non-standard “__property” statements.

Is there a way to compile code that uses “__property” statements on a Linux machine using Clang or does the -fborland-extensions only apply to Windows versions of Clang? I’ve tried setting the flag, but the compiler (3.4.2) gives me an “unknown type name” error.
