Refs #4195. Fix handling of array sizes for Windows.
MSVC doesn't allow non-static const ints to be array size parameters. gcc seems to be able to figure out that the const int is okay.

To do the job properly, this really needs to be tested by someone who has access to an LET data file.....

It took about 2 minutes to load a recent LET Nexus file (from cycle 11-4) and about 3/4 minute to load a Raw file. There were no complaints about memory (Windows 7).

The Nexus file used 28,754 KB memory and the Raw file 1,669 MB.
