New description:
PPL 1.0 uses some libm long double functions (floorl, frexpl) as soon as
it detects the long double type is available and looks functional.
Unfortunately the Cygwin's libm does not provide such function, and we do
not build Cephes on Cygwin.
The easy solution is to use plain double precision in place of the
extended ones (with a std:: prefix, as PPL also defines its own floor
function).
This is what is implemented in 1.1.pre* releases of ppl available at
http://bugseng.com/products/ppl/download/ftp/snapshots/.
There was a similar report archived at http://www.cs.unipr.it/pipermail
/ppl-devel/2012-September/018538.html.
