IBM Update:
Run the libdfp testsuite in the build directory with:
make check

The hardware variant of libdfp on s390 produces failures in the testsuite:

In the build dir after make check: ls -l *.out

Hi Joe, John,

based on our calls libdfp should get these fixes for R 6.1.
If verification fail we should open a new BZ.

Seems we can just continue to use this ?

I checked the src rpm for the latest RHEL 6.1 supplemental and these fixes are not in place.
