ORCA/C 2.2.0 B7 supports nearly all the features required by C17, apart from wide character support and some floating-point library features.

For installation instructions, see the readme. For details on what has changed, see the release notes.

This is an update package designed to be installed on top of an existing copy of ORCA/C 2.1 or later. Note that the disk image must be treated as a hard drive image or high-density floppy image. If you need to use an 800KB floppy, place the SHK file on it instead of using the disk image.

Also: An updated ORCALib for GNO/ME 2.0.6.

This is an updated version of the ORCALib library suitable for use with GNO 2.0.6. This contains the same updates as the standard ORCALib distributed with ORCA/C 2.2.0 B7, except that under GNO certain portions of the C standard library (such as <stdio.h>) are not included in ORCALib because they are implemented by GNO’s libc. For more information about this GNO version of ORCALib, see the readme.

You should only use this if you are using ORCA/C under GNO. The standard version of ORCALib suitable for use under the ORCA shell is included with the ORCA/C 2.2.0 B7 release.
