Bugs fixed in CIAO 4.12

The following is a list of bugs that were fixed in the CIAO 4.12 software release.

Sorting a column with special IEEE values (NaN, +/- Inf) results in a partially sorted file.

IEEE special values: NaN, -Inf, and +Inf, do not follow the same < and > comparison rules as real, finite values. This causes problems when dmsort tries to sort these columns which may result in the file being incorrectly partially sorted.
