Sorry, it appears I'll have to backpedal on this one.  I had a
s_frexpl.c sitting in my libm/ src directory together with a
change to its Makefile to build it, probably pulled from newer
NetBSD in an earlier attemt to get newer goffice 0.10 to build,
and subsequently forgotten about.

Suggestions for cheesy workarounds accepted -- cast to double and
use frexp?  (Yes, you would lose precision and range(?) that way.)

BTW, it doesn't look like the frexp(3) man page in 7.0_RC3 has
been extended to document the frexpl() function...
