Looking at:

cd lib/ogsf

grep MAX_VO *
gsurf.h:#define MAX_VOLS       12
GVL2.c:static int Vol_ID[MAX_VOLS];
GVL2.c:    if (Next_vol < MAX_VOLS) {
gvl_file.c:#define MAX_VOL_SLICES         4
gvl_file.c:#define MAX_VOL_FILES        100

I feel that MAX_VOL_SLICES and MAX_VOL_FILES should probably go into
gsurf.h and that MAX_VOLS should match MAX_VOL_FILES.
