--- Comment #19 from Joshua Cogliati <jjcogliati-r1 at yahoo dot com> --- Created attachment 30913 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30913&action=edit Patch to add -Wfloat-conversion option against trunk This version is against gcc trunk (rev 202818). It now bootstraps. It adds about ten casts so that the existing float conversions in gcc are now explicit instead of implicit so that gcc can bootstrap even with the new warning.
