Assume that we have rint().

2020-02-21T19:30:47Z

Windows has this since _MSC_VER >= 1200, and so do all other live platforms according to the buildfarm, so remove the configure probe and src/port/ substitution. This is part of a series of commits to get rid of no-longer-relevant configure checks and dead src/port/ code. I'm committing them separately to make it easier to back out individual changes if they prove less portable than I expect.

Rethink how to get float.h in old Windows API for isnan/isinf

2018-07-11T13:11:48Z

We include in every place that needs isnan(), because MSVC used to require it. However, since MSVC 2013 that's no longer necessary (cf. commit cec8394b5ccd), so we can retire the inclusion to a version-specific stanza in win32_port.h, where it doesn't need to pollute random .c files. The header is of course still needed in a few places for other reasons. I (Álvaro) removed float.h from a few more files than in Emre's original patch. This doesn't break the build in my system, but we'll see what the buildfarm has to say about it all.

Upgrade src/port/rint.c to be POSIX-compliant.

2015-03-25T19:54:18Z

The POSIX spec says that rint() rounds halfway cases to nearest even. Our substitute implementation failed to do that, rather rounding halfway cases away from zero; and it also got some other cases (such as minus zero) wrong. This led to observable cross-platform differences, as reported in bug #12885 from Rich Schaaf; in particular, casting from float to int didn't honor round-to-nearest-even on builds using rint.c. Implement something that attempts to cover all cases per spec, and add some simple regression tests so that we'll notice if any platforms still get this wrong. Although this is a bug fix, no back-patch, as a behavioral change in the back branches was agreed not to be a good idea. Pedro Gimeno Fortea, reviewed by Michael Paquier and myself

Remove cvs keywords from all files.

Avoid changing the sign of zero. Per buildfarm failures.
