Subject: gpsrinex: Fix build on OpenBSD.

On OpenBSD, apparently _XOPEN_SOURCE 500 isn't good enough to get
isfinite().  Changing it to 600 fixes it.

TESTED:
(With subsequent fix included)  Ran "build-all check" on Mac Pro 10.9,
Mac Pro 10.14, MacBook Pro 10.9, PowerBook 10.5, VMs for OSX
10.5-10.13, Ubuntu 14.04, CentOS 7, Fedora 25, FreeBSD 10.3, OpenBSD
5.6, OpenBSD 5.6 32-bit, NetBSD 6.1.5, and Beaglebone (arm) Debian 7.
