Yes, I noticed that macro, and I could use it if necessary (although I 
see no reason to replace floor in this context except to silence the 
warning).   But I was curious to know what Jordi's suggestion was to do 
it "without touching" the code; to me, inserting #ifdefs counts as 
"touching".  :-)

(Do I also have to include declarations of gnulib::floor etcetera, or is 
the compilation somehow set up so that the gnulib math.h replaces the 
<cmath> header?)
