Is there a way for an application linked to a netcdf library to

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;

OK, that was the only method I had come up with; I was hoping I was
missing something.
I have an application that I want to normally write a classic netcdf-3
file, but if the netcdf library was compiled with the netcdf-4 option
enabled, it should create a netcdf-4 file. It looks like the netcdf.h
file is the same for both options and I don't see any api function that
would give the information.
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.

Thanks, that sounds like a good idea...
