structs containing those arrays. Encapsulating the arrays in this way
makes it easier to write and think about pointers to these types, casts
to/from these types, etc.
An interesting side-effect that we probably should *not* rely on is
that the struct-encapsulation changes the alignment so that some GCC
warnings about casts that increase the alignment requirement of the
operand go away. Warnings like that have to be taken seriously: I will
add -Werror=cast-align to the default compiler flags so that they stop
the build quickly.
GCC warnings led me to some surprising casts in test/trefer.c. I found
that it was possible to make many simplifications after introducing the
struct-encapsulation that I described, above.
In test objcopy_ref `same_file` is assigned but never used. Delete it.
including the merge of `hdffv/hdf5/develop`, back to the branch that Vailin and
I share.
Now I need to put this branch on a fork with a less confusing name than
vchoi_fork!
