Hi Martin,

The really-quick-fix is to increase the size of:

      parameter ( MNC_MAX_CHAR =     40 )

in pkg/mnc/MNC_SIZE.h to 80+ characters.  And the downside of that
quick-fix is that MNC will consume a lot more RAM.  But perhaps thats OK
for you.

After a few off-list complaints, I drastically reduced the memory
footprint of MNC by shrinking the size of most strings within the lookup
tables.  The change also improved path handling for filenames--much
longer paths are now allowed.  But the change also caused the above
warnings.  I'm working on a modification that will increase the size of
the text strings used for attributes (while keeping the other strings at
the current, shorter size) and will check it in soon.
