Hello.
New version of the patch below. Differences from previous versions:
- The GA68 variable has been renamed to A68. (This has been also
changed in the corresponding autoconf patches.)
- Added a section 'Algol 68 Support' to the manual.
- Added a test t/a68-demo.sh.
commit c33511e6df2b23de3040484a56cc0efdff5c0691
Author: Jose E. Marchesi <jose.march...@oracle.com>
Date: Fri Jan 24 00:20:27 2025 +0100
Add support for the Algol 68 programming language.
* NEWS: Add entry for Algol 68.
* doc/automake.texi (Algol 68 Support): New section.
* bin/automake.in: Call register_language for Algol 68.
(resolve_linker): handle A68LINK.
(%_am_macro_for_cond): Add entry for am__fastdepGA68.
* configure.ac: Look for ga68 and set GNU_GA68 and GNU_A68FLAGS if fuond.
* lib/Automake/Variable.pm (%_ac_macro_for_var): Add entries for GA68
and GA68FLAGS.

+
+Automake includes support for Algol 68, using GCC.
+
+Any package including Algol 68 code must define the output variable
+@code{A68} in @file{configure.ac}; the simplest way to do this is to use
+the @code{AC_PROG_A68} macro (@pxref{Particular Programs, , Particular
+Program Checks, autoconf, The Autoconf Manual}).
+
+A few additional variables are defined when a Fortran 77 source file is
+seen:
+
+@vtable @code
+
+@item A68
+The name of the Algol 68 compiler.
+
+@item A68FLAGS
+Any flags to pass to the Algol 68 compiler.
+
+@item AM_A68FLAGS
+The maintainer's variant of @code{FFLAGS}.
+
+@item A68COMPILE
+The command used to compile an Algol 68 source file. The file name is
+appended to form the complete command line.
+
+@item A68LINK
+The command used to link a pure Algol 68 program or shared library.
