Dec 16 07:22:01 <JohnJ> 07:03:35> Is feenableexcept() legitimate in Pioneer?
Dec 16 07:22:01 <jpab>  07:10:19> legitimate?
Dec 16 07:22:01 <JohnJ> 07:14:17> Well, it's glibc 2.1
Dec 16 07:22:01 <JohnJ> 07:14:22> Not technically POSIX.
Dec 16 07:22:01 <JohnJ> 07:15:27> I guess I can do #ifdef _GNU_SOURCE
Dec 16 07:22:01 <JohnJ> 07:16:02> or __USE_GNU. This documentation is not clear on the point.
Dec 16 07:22:01 <jpab>  07:17:11> in the header it's behind __USE_GNU
Dec 16 07:22:01 *       JohnJ 07:17:28> goes with that
Dec 16 07:22:01 <jpab>  07:17:47> however, I suspect that's intended as an internal macro only
Dec 16 07:22:01 <jpab>  07:18:13> I assume this is just to try to catch some errors?
Dec 16 07:22:01 *       Brianetta 07:18:27> merges jpab's changes
Dec 16 07:22:01 <JohnJ> 07:18:33> I use it around the autopilot. It catches a lot :-)
Dec 16 07:22:01 <jpab>  07:18:54> yeah
Dec 16 07:23:13 <robn>  feenableexcept is C99
Dec 16 07:23:57 <jpab>  robn: is it?
Dec 16 07:24:24 <robn>  These eleven functions were defined in C99, and describe  the  handling
Dec 16 07:24:24 <robn>         of  floating-point  rounding  and  exceptions  (overflow,  zero-divide,
Dec 16 07:24:24 <robn>         etc.).
Dec 16 07:24:27 <robn>  my manpage says so
Dec 16 07:24:35 <robn>  CONFORMING TO
Dec 16 07:24:35 <robn>         IEC 60559 (IEC 559:1989), ANSI/IEEE 854, C99, POSIX.1-2001.
Dec 16 07:24:51 <jpab>  robn: yeah, but "these eleven" functions doesn't include feenableexcept
Dec 16 07:24:55 <jpab>  robn: that one is further down the manpage
Dec 16 07:25:41 <robn>  oh I didn't even look at the synopsis. I assumed "man feenableexcept" would get me to the right place
Dec 16 07:25:44 <robn>  punks
Dec 16 07:25:46 <robn>  ok sorry :)
Dec 16 07:26:18 <JohnJ> gah, miniz.c not compiling today.
Dec 16 07:29:15 <jpab>  I don't see any mention of __USE_GNU in documentation
Dec 16 07:30:14 <JohnJ> _GNU_SOURCE there?
Dec 16 07:30:17 <jpab>  yeah
Dec 16 07:30:43 <JohnJ> I guess _GNU_SOURCE #defines __USE_GNU
Dec 16 07:30:53 <robn>  _GNI_SOURCE is what you want
Dec 16 07:30:55 <JohnJ> You reckon I should use _GNU_SOURCE then?
Dec 16 07:30:57 <JohnJ> k
Dec 16 07:31:01 <robn>         #define _GNU_SOURCE         /* See feature_test_macros(7) */
Dec 16 07:31:01 <robn>         #include <fenv.h>
