[Octave-bug-tracker] [bug #51630] BIST test for log2 fails on Windows

[Markus Mützel]

Follow-up Comment #3, bug #51630 (project octave):

Windows returns the same like I get in Linux:

>> [e f] = log(0)
e = -Inf
error: element number 2 undefined in return list


Yes, we could handle +/-Inf conditionally (maybe for Windows only?). But isn't
that what gnulib is for?
Maybe it would also help to use a newer gcc? gcc 4.9.4 seems to be out of
support now. My "native" gcc is version 6.3.0 on Ubuntu 17.04.
I don't know which "implementation" is referred to by the cppreference site.
The compiler? The C libraries? The OS?
