I am very  happy to announce that,  after almost a year  in the works,
today the  Algol 68  front-end has  been merged in  GCC proper  in its
development trunk branch.  This means  that we are no longer off-tree,
and that GCC  16 will be featuring a full-fledged  and modern Algol 68
compiler once it gets released.

An Algol 68 module

This doesn't  mean the  work is  done.  The  modules system,  which is
already  functional,  needs to  be  completed  and polished,  parallel
clauses are still to be implemented,  and the quality of the generated
code should be generally improved.  We  also want to replace the boehm
GC with  a tightly integrated  customized, exact one, and  to continue
modernizing  and   expanding  the   language,  always   carefully  and
respectfully, via GNU extensions: exception handling, FFI, etc.

At  this point  I would  like  to thank  Marcel van  der Veer,  Pietro
Monteiro, Mohammad-Reza Nabipoor, Thomas Schwinge, Sam James, Matthias
Klose, Iain  Buclaw, Andrew  Pinski, Segher Boessenkool,  Iain Sandoe,
the GCC global reviewers and the overall GCC community.  Without their
help, and Marcel's nifty Algol  68 parser, this front-end would simply
not exist.

And now, the real fun starts... ;)
Happy algoling!
