Hi Xavier.

Can't you do a do_version()?
In readfile.c you can see a lot of parameters that need to be updated
over Blender version.
If what you need is a simple offset for old blender files work in the
same way as new blender files (with this bug fixed), this should work.

I didn't see the bug or this part of the code, but do_version()
sometimes is the better way to go.
