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