undefined errors in trunk's libbackend

[Bobby McNulty <snyder100 at bellsouth dot net>]

I keeping getting this error, though it gets less and less each day.
platform it i686-pc-cygwin.
I am not sure if this has been discussed before or similar discussions.
gmp 4.2.1 and mpfr 2.2, up to date as of today.
