System: NetBSD smistad.uninett.no 6.1.4 NetBSD 6.1.4 (MAANEN) #2: Sat May 17 15:02:30 CEST 2014 he@smistad.uninett.no:/usr/obj/sys/arch/i386/compile/MAANEN i386
Architecture: i386

>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).

 It is hidden under __HAVE_LONG_DOUBLE (this has
 been the case since before the bug report).

 ... although it's possible it was not in 6.1.
