Compiler backwards compatibility

Hi,

Okay, I checked these options, but 'r7' is a little too strong, as I need some of the features in any case. 

What options should I use in order to get R9 compatibility? The current complaint is for opcode 112, which should mean I have to use no_new_apply, but are there more?

best regards,
Vlad
