We are pleased to announce GNU Guile release 2.1.6.

Guile 2.1.6 is the sixth pre-release in what will eventually become the
2.2 release series.  We encourage you to test this release and provide
feedback to address@hidden.

Saw this one last round.  Mac OS, now gcc-6.3.0:

;;; ("address@hidden" 1.0 -0.0)
FAIL: numbers.test: string->number: valid complex number strings

I am going to see if I can generate the assembly.

Short story: scm_c_make_polar is broken for the Mac.  Guile needs to decide if it want to use __sincos() on Mac, or suppress optimization, or ...

a patch, with which make check passes all tests on macOS 10.12.2, aka Sierra:
