>Description:
        While trying to package math/gnumeric to version 1.12.11,
        I first find that gcc claims the (implicit) declaration of
        frexpl in misc/goffice-0.10 (after updating it to 0.10.17)
        goffice/math/go-dtoa.c is conflicing with the builtin version.
        However, just adding the declaration just leads to a linking
        error when linking gnumeric that frexpl is missing.

>How-To-Repeat:
        Try to build a program using frexpl() with the

        extern long double frexpl(long double, int*);

        prototype.  Watch it fail.
>Fix:
        Sorry, don't know.

        It seems that Apple, Illumos and Linux is using
        code from AT&T as part of the "ast" package for
        implementing this (and probably other) functions,
        but I also can't find traces of that in pkgsrc
        (not really surprising).
