Details:

The first unit test in file bim1c_norm.m fails randomly.  This is the recipe
for triggering the bug:


octave:1> pkg load bim
octave:2> while 1
 L = rand (1); V = rand (1); m = linspace (0,1,5).^2;  m *= L;
 u    = V * ones (size (m))';
 uinf = bim1c_norm (m, u, 'inf');
 uL2  = bim1c_norm (m, u, 'L2');
 uH1  = bim1c_norm (m, u, 'H1');
 assert ([uinf, uL2, uH1], [V, V*sqrt(L), V*sqrt(L)], 1e-12);
endwhile
error: ASSERT errors for:  assert ([uinf, uL2, uH1],[V, V * sqrt(L), V *
sqrt(L)],1e-12)

  Location  |  Observed  |  Expected  |  Reason
    (3)        0.051682     0.051682     Abs err 4.7937e-12 exceeds tol 1e-12
by 4e-12


The patch attached to this bug report fixes the problem.
