Kinetic model option causes compilation error when compiling HYDRAD

[wtbarnes]

Using the USE_KINETIC_MODEL preprocessor directive yields the following error when compiling HYDRAD.exe,

../source/eqns.cpp:2943:10: error: use of undeclared identifier 'iNumCells'
iIndex = iNumCells-2;
         ^
../source/eqns.cpp:2951:10: error: use of undeclared identifier 'iNumCells'

I don't need the kinetic model for anything. I just figured that this bug should be documented in some way as it has popped up a few times and I get confused by it each time.
