scummvm/gob/parse.cpp
Joost Peters f35ac50111 Some inter_variables cleanup. 
Now it should store all variables in the native endianness, instead of storing half in LE and the other half in the native endianness.
Addresses and assignments can be tracked by modifying the macros if necessary.
Also, meaningful constants can now be assigned to script variable numbers (if one were so inclined)
