--- Comment #5 from Vincent Lefèvre <vincent-gcc at vinc17 dot net> --- (In reply to Vincent Lefèvre from comment #4) > I can see the same problem under Linux (gcc110.fsffrance.org). In case this wasn't clear, the architecture is also a PowerPC. The double-double format comes from the PowerPC ABI, and isn't directly related to the OS itself (FYI it was also used under Mac OS X / PowerPC). Thus the summary of this bug should be changed to: LDBL_EPSILON is wrong on PowerPC
