Option 1: check whether the implementation supports "long long", and
define dglInt64_t as something else (e.g. "long") if it doesn't.
You can use the configure macro:
which should define HAVE_LONG_LONG if the type exists.
The disadvantage is that the file format will be incompatible with
systems which do have a 64-bit integral type.
Option 2: change the nnCost field to double, and modify the code which
reads and writes the nnCost field to read/write 2 32-bit values and
convert them to/from a double value.
