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

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

scheme@(guile-user)> (define z (string->number "address@hidden"))

scheme@(guile-user)> (eqv? (imag-part z) -0.0)

$7 = #f

Sorry to keep posting on this.  I will stop soon.  I seem to get different problems every time I build 2.1.5 on my Mac.  I am using some different config options (e.g., with and without —disable-shared) and different compilers.  The above issue does not show up with the current build.   Note the following separate builds that give different values for the above:

mwette$ pwd

/Users/mwette/proj/scheme/guile/guile-2.1.5

mwette$ meta/guile -c '(display (eqv? (imag-part (string->number "address@hidden")) -0.0))'

#f

mwette$ pwd

/Users/mwette/proj/scheme/guile/guile-2.1.5-2

mwette$ meta/guile -c '(display (eqv? (imag-part (string->number "address@hidden")) -0.0))'

#t
