  The Banks-Casher relation links the spectral density of the Dirac operator
with the existence of a chiral condensate and spontaneous breaking of chiral
symmetry. This relation receives corrections from a finite value of the quark
mass, a finite space-time volume and, if evaluated on a discrete lattice, from
the finite value of the lattice spacing a. We present a status report of a
determination of these corrections for Wilson quarks.
