Quoth  perldoc -f pack on my 5.8.9 Perl:

D   A long double-precision float in the native format.
    (Long doubles are available only if your system supports long
    double values _and_ if Perl has been compiled to support those.
    Causes a fatal error otherwise.)
Also see pack. I'm not sure about the red coloration; maybe it flags a feature not supported by all word widths/compilation options. (Actually, I suspect a documentation problem since everything in the table (update: including things like  x X @ that are as old as the hills) from line 41 on is both red and italic.)

Give a man a fish:  <%-{-{-{-<
