[Insight-developers] Statistics class changes in current CVS bothers GCC 4.0.1

[Kent Williams]

I ran into a little problem this morning compiling ITK tests.  This may 
be compiler specific, but GCC 4.0.1 seems to need some help to pull 
typedefs down from the superclass.  The following patch gets me a clean 
compile at least, but since I've never worked on any of this code I am 
leery of just checking in my changes.

The error message I get is 'TotalFrequency does not define a type', and 
in looking through the headers, it seems that these classes don't 
locally typedef TotalFrequncyType, but the superclass does.
