Change this code block:

gaint read_metadata (struct gafile *pfi) {
struct gavar *pvar;
gaint rc,i,ii,j,len,ngatts,natts,ndims,nvars,status,oflg,dummy;
size_t sz,size=0;
#if USEHDF ==1
int32 ndsets,dimsize,sds_id,dim_id,dtype,ndatts;
int32 dim_sizes[H4_MAX_VAR_DIMS],rank;
char sdsname[H4_MAX_NC_NAME+1];
char name[H4_MAX_NC_NAME+1],dimname[H4_MAX_NC_NAME+1];
#endif

To this code block instead:

gaint read_metadata (struct gafile *pfi) {
struct gavar *pvar;
gaint rc,i,ii,j,len,ngatts,natts,ndims,nvars,status,oflg,dummy;
size_t sz,size=0;
char name[300];
#if USEHDF ==1
int32 ndsets,dimsize,sds_id,dim_id,dtype,ndatts;
int32 dim_sizes[H4_MAX_VAR_DIMS],rank;
char sdsname[H4_MAX_NC_NAME+1];
char dimname[H4_MAX_NC_NAME+1];
#endif

Yes, you can also build wtih hdf4 -- but you must use the --disable- 
netcdf option when compiling that library.
