And as a tangential point, that's not accurate for C2X, where DFP is an optional standard feature, but it's probably reasonable to keep the diagnostic saying "ISO C does not support" under its existing conditions until someone actually reviews and updates the DFP support for the differences between the old TR 24732:2009 and the newer TS 18661-2 / C2X version (not sure how big those differences are, but not much has changed in the DFP support in GCC lately). -- Joseph S.
