From Eddy:

1) Added to LinkDef.h the NormalEqn function from TDecompChol . They
got
    lost in this file during the transition to the templated version of
the matrix library .

2) Replaced in the templated code everywhere references to DB_EPSILON
and DBL_MIN
    by the templated version through <numeric_limits> .
