#6346 — ORCA/C 2.3.0 B1

Hi folks,

I've just released ORCA/C 2.3.0 B1. The full source code is available on 
GitHub, and a binary update package is on the releases page:

https://github.com/byteworksinc/ORCA-C/releases/tag/orcac-230b1

This is the latest version of ORCA/C, the C compiler for the Apple IIGS. 
This update contains various enhancements and bug fixes, including 
support for many features from the recent C23 standard. Major new 
features added since ORCA/C 2.2.1 include:

* C23 language features
   - New spellings without underscores for some keywords like bool
   - true, false, and nullptr predefined constants
   - typeof and typeof_unqual operators
   - #elifdef and #elifndef preprocessor directives
   - #embed preprocessor directive for embedding data from files
   - Type inference using auto in variable declarations
   - Bit-precise integer types _BitInt(N) and unsigned _BitInt(N)
   - Variable-length array types (but not VLAs as local variables)
   - Optional support for C23 rules requiring function prototypes
   - Enumeration constant values can be outside the range of int
   - Underlying types for enumerations can be explicitly specified
   - Structure, union, or enumeration definitions can be repeated
   - Labels are allowed before declarations or at the end of a block

* C23 library features
   - Many new floating-point math functions
   - New <stdbit.h> header with many bit utility functions
   - Support for binary numbers in printf and scanf
   - Various new library functions such as memccpy and strdup

Note that this update must be applied on top of an existing copy of 
ORCA/C 2.1 or later. If you don't already have that, it's available as 
part of the Opus ][ collection sold by Juiced.GS.

There is also a corresponding update to the GNO-specific version of 
ORCALib, which you should get if you are using ORCA/C under GNO:
