Updated gcc-ia16 toolchain

TK Chia writes: "I have uploaded new packages for the gcc-ia16 toolchain, at Github, tag 20190101. This is a DJGPP/MS-DOS-hosted (32-bit x86) port of the GNU C and C++ compiler toolchain to the IA-16 target (16-bit Intel x86), by Rask Ingemann Lambertsen, Andrew Jenner, myself, and various contributors. The toolchain itself is 32-bit, but it will output 16-bit code. Besides fixing the package descriptions to make them fit onto single lines, I have also included in the packages some compiler optimizations and other minor features that I recently implemented." The notes and change log are in the release. See also the update at Github, tag 20190113 that fixes the URL for GNU MPFR.

FreeDOS 1.3 RC1 is ready for testing!

The first release candidate for FreeDOS 1.3 is now available for testing! FreeDOS 1.3 RC1 is meant as a test release, and we do want your feedback. Please discuss in either the freedos-user or freedos-devel email lists.

FreeDOS 1.3 RC1 is available as several installation media: USB stick images, VMDK images, and CD images. Two prototypes of LiveCDs are being provided with RC1. However, one will be discarded for the FreeDOS 1.3 final release, depending on feedback. Both types have some live FreeDOS packages at boot and support temporarily installing/removing more by using FDIMPLES. Also, both will automatically start networking support when used inside VirtualBox or VMWare. For other environments, you will need to manually start it. So, let your voice be heard on which (if any) LiveCD you prefer. Download FreeDOS 1.3 RC1 and let us know what you think.
