Enclosed is a patch against the 1.4.0 HFA driver source implementing no-data value support. Only partial BASEDATA support in HFAField::SetInstValue() has been implemented to support this, due to time crunch issues on my end; specifically, only 1x1 BASEDATA arrays of type double are handled. Setting and retrieving the no-data value has been tested and verified in at least simple cases to work correctly; the HFA statistics generation routines correctly honor the set no-data value; and gdalinfo correctly reports the set no-data value.
