Yes, but it's not exactly elegant :-)
#include <netcdf.h>
/* Returns 1 if linked to library with netCDF-4 features enabled, otherwise 0 */
int
is_netcdf4(void) {
int ncid;
int stat = nc_create("/tmp/tmp.nc", NC_NETCDF4, &ncid);
if(stat == NC_ENOTNC)
return 0;
return 1;
}

We'll consider adding such a function in addition to the current
nc_inq_libvers() function that returns a string for which version of the
library source was used to build the library, but doesn't specify with
which features the library was built.
