At least as I read the GCC documentation, if GCC supports a builtin
floorl() at all, it will always treat floorl() and
__builtin_floorl() the same (it's reserved in C90 and defined in C99, so
nobody should ever write C code assuming floorl() won't be treated in
that afshion).
In addition, the GCC 3.3.6 manual says nothing about __builtin_floorl(),
so it probably won't help to use it. If it appears to help, there's
probably something else going on.
Also, GCC appears not to like "#ifdef (__GNUC__)", as the parentheses
mean it's testing an expression, not a macro name.

That better indicates what they do - they don't supply floor(), as
that's a standard math.h feature dating back before C89, they supply
floorl().
