These sound like modernish floating functions, and they're apparently
not part of our math library (yet). However, frexp()/frexpf() and
ldexp()/ldexpf() exist, but where frexp() and ldexp() take a double
argument, frexpl()/ldexpl() appear to take a "long double". Why a
shell needs these functions, though, is a bit beyond me...
A quick & dirty fix might be to use frexp() / ldexp() instead, and
cast the offending argument from "long double" to "double" (or let
prototype visibility do that for you).
