'truncf' and 'floorf' belong together but I can state that the latter
is definitely present:

Why do we care? Just call floor(), which is in the ANSI C standard.
The extra precision won't hurt anyone, and there is zero performance

Is this for JSBSim standalone, or for FlightGear/JSBSim?
For the later, the entry for borland in SimGear/simgear/compiler.h might
be outdated.
