As far as I understand the general state of DFP support in GCC: the basic 
functionality generally works without needing much maintenance, but no-one 
is actively fixing DFP bugs or updating the DFP support for TS 18661-2 / 
TS 18661-3, and no-one has ever hooked the DFP support up to the support 
for the C front-end to manage excess precision, so that support is only 
active for binary floating point.
