gnulib warnings when compiling Faddeeva.cc

[Jordi Gutiérrez Hermoso]

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:
warning: call to 'floor' declared with attribute warning: The symbol
::floor refers to the system function. Use gnulib::floor instead.
/home/jordi/coding/vcs/octave-devel/liboctave/cruft/Faddeeva/Faddeeva.cc:877:
warning: call to 'floor' declared with attribute warning: The symbol
::floor refers to the system function. Use gnulib::floor instead.
/home/jordi/coding/vcs/octave-devel/liboctave/cruft/Faddeeva/Faddeeva.cc:902:
warning: call to 'copysign' declared with attribute warning: The
symbol ::copysign refers to the system function. Use gnulib::copysign
instead.

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