Scientific calculations using long double

Hello:
Currently, I am trying to solve a problem that requires the
calculation of Airy functions for big arguments. Because Airy
functions diverge rapidly for positive values, the results of the
calculation quickly produces overflow (or underflow depending on which
Airy function is used) for values of the argument greater than about
100 when using double. Because of this, I need to find a routine that
calculates Airy function producing results of type long double. Can
anyone make any suggestions??? I have tried GNU's GSL library, which
works with long doubles in most functions, but unfortunately, it
doesn't work with long doubles for special functions. Thanks...
