With patches I can compile and run “make check”.  But now I have one failure:t tests/numbers.test line 1663: (“#i1@-0” 1.0 -0.0).  

This wants the following to produce #t, but it does not:

scheme@(guile-user)> (define z (string->number "#i1@-0"))
scheme@(guile-user)> (eqv? (imag-part z) -0.0)
$7 = #f
