source: trunk/FACT++/src/InterpreterV8-4.h@ 20037

Last change on this file since 20037 was 20023, checked in by tbretz, 5 years ago
This adds a version that was tested at least with V8 6.8 and a wrapper to switch between both -- using ifdefs in the code is not reaonable as there would be too many.
