--- Comment #10 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- This has nothing to do with 84717. The present bug is simply invalid; GCC is acting as specified in the C standard for excess precision. 84717 is arguably a legitimate issue about lack of documentation for an extension (albeit an extension taken from an old TR).
