Look at the generic subdirectory.  This part is written in C.

No, they should default to "natural".  I think they do unless you have something
on the contrary on your preferences file. If the original default for registers is
not "natural" anymore it must be changed back.

GDB will "print" them for us in the right format.  We don't want to mess with
types and languages specific in the Insight code.

That sounds like an user error.  There must be entries in their preferences file.

And if they change the registers to "natural" and cleanly exit Insight that default
should persist.
