Problems with testing PNETCDF 1.6.1

Hi, Eric

For the large file tests, the error is caused by a oversight of using a wrong flag.
Line 81 of file large_files.c should have used NC_64BIT_DATA, instead of NC_64BIT_OFFSET.
This error has been fixed in the pre-release of 1.7.0.pre1. Could you give it a try?

As for the FLASH-IO test, could you try running it alone? I.e. cd to the folder
benchmarks/FLASH-IO and run "make ptest" there. In the meantime, please send me
the file config.log.
