Ann: HAC v.0.21

[Gautier write-only address <gautier_niouzes@hotmail.com>]

HAC (HAC Ada Compiler) is a quick, small, open-source Ada
compiler, covering a subset of the Ada language.
HAC is itself fully programmed in Ada.

Web site: http://hacadacompiler.sf.net/
From there, links to sources, and an executable for Windows.

Source repositories:
#1 svn: https://sf.net/p/hacadacompiler/code/HEAD/tree/trunk/
#2 git: https://github.com/zertovitch/hac

HAC is also available through Alire : https://alire.ada.dev/

* Main improvements since v.0.2:

  - Added Virtual Machine Variables, another mean for exchanging
      data between the HAC program and the program hosting the VM.
  - SmallAda's tasking is working again in its HAC reincarnation
     - at least, for some simple tasks.
  - HAL becomes HAT (HAC Ada Toolbox), to avoid name collision
     with HAL = "Hardware Abstraction Layer".

Enjoy!
