s always within 0.03 of 23.40 over multiple runs. Incidently, while the real-8 compile output 271828665.96115601, the real4 compile output 67108976. This does, then, seem to be an x86-64 issue. -JimC -- James Cloos OpenPGP: 1024D/ED7DAEA6

Wierd manual link and resulting dead link

2013-04-26 Thread James Cloos
Presumably a side effect of the info->html process, which uses U+2D in place of U+20 when generating the URIs from the info section names. One fix would be to use Builtin rather than Built-in in the secion name. Or update the links in the 4.8 what's new to match the current html. -JimC -- Jam

nificant amount of compiling would fail to have their own CFLAGS (et al) with the options which they prefer. Forcing -Wall for those who did not ask for it is <...words.escape...>. -JimC -- James Cloos OpenPGP: 1024D/ED7DAEA6

efault which tend not to false-positive and provide useful, beneficial information when triggered, then it is reasonable to look into starting to default-enable them. Turning *all* of them on willy-nilly is not. -JimC -- James Cloos OpenPGP: 1024D/ED7DAEA6

many years it has been since I last read that section of the manual), but adding a new option to contain the default warnings fits well with my thesis. Something like -Wdefault-warnings is a reasonable choice, for the reasons already mentioned in this sub-thread. -JimC -- James Cloos OpenPGP: 1024D/ED7DAEA6
