Testsuite Failure in CVS head

I just updated and rebuilt maxima.  There was one testsuite failure:

Running tests in rtest3: 
********************** Problem 70 ***************
Input:
block([fpprec : 35], ev(ans, x : 1, bfloat) - ev(ans, x : 0, bfloat))


Result:
5.7791601820424019599988308251707781b-1

This differed from the expected result:
5.7791601820424019599988308251707781b-1


I may be going blind, but the results look the same to me.
