Re: gnulib warnings when compiling Faddeeva.cc

[Júlio Hoffimann]

Also copysign() is C++11: http://en.cppreference.com/w/cpp/numeric/math/copysign

For that we have no option other than switch to gnulib implementation.

I encountered the same warning, making it explicit with std::floor() doesn't help.

It must have something to do with the build system? Why is gnulib::floor() preferred over std::floor()?

I just noticed these:

/home/jordi/coding/vcs/octave-devel/liboctave/cruft/Faddeeva/Faddeeva.cc:
In function 'cmplx Faddeeva::w(cmplx, double)':
/home/jordi/coding/vcs/octave-devel/liboctave/cruft/Faddeeva/Faddeeva.cc:689:

instead.

Is it ok to perform the suggested replacements for gnulib functions?
