While nosing around POSIX.xs I wondered if cosh() etc used the long-double coshl() etc in a USE_LONG_DOUBLE build.

I see modf() uses Perl_modf() which gets the long double modfl(). Perhaps the same would be easy for floor() and ceil() with Perl_floor() and Perl_ceil(). I suppose others would want configure checking to be sure of the ldbl funcs libm actually has or doesn't have.
