"man floor(3)" says that link should be done with -lm, so I think it's
probably just thanks to a tolerant linker that the problem has not
emerged before (I don't know then if this level of tolerance is the
least we can expect or if gcc is a very patient guy).
Is it safe enough to add -lm to the linker flags for all the other
distro? I think so - but I'm no authority on linking at all. I don't
think instead we should be as strict as add --no-undefined: maybe
having a mandriva builder in the build farm to check for regressions
would be enough (it would be great if Christeas could provide it).
