For the same reason I'm not using MINC 1.x. :)

That would work great.  I had actually done that (though without the
else) in a previous test.

However, one could argue that since MAX_NC_OPEN is gone from NetCDF (I
searched the whole NetCDF 3.6.3 source tree and MAX_NC_OPEN appears only
where it's defined, in other words, it's deprecated in 3.x also.) that
it would be better to purge MINC of this constant.  Its current value of
32 will never change.

BTW, everything seems to be working fine built against 4.0.1.
