It's not going to help.  The offending code (below, from basic.h) is
NOT conditional on VIO_PREFIX_NAMES.

typedef enum {
               OK,
               ERROR,
               INTERNAL_ERROR,
               END_OF_FILE,
               QUIT
             } VIO_Status;

The enum VIO_Data_types in multidim.h, which has the offending enum
value "DOUBLE", is similar.

In the past, I've worked around this kind of problem by partitioning
my code so that a given file never needs to include conflicting
headers.

Some things to try:

 * Move includes from the .h file into the .c file.
 * If you need a type in the .h that is only passed around by
   pointers, you can use a forward declaration to avoid #including the
   header defining it.
 * Creating a type that encapsulates the volume_io type can help achieve
   the first two points.
