Hello.
This patch adds support for the Algol 68 programming language to Automake. It is based on the Algol 68 GCC front-end, which is currently under development [1]. A WIP series got sent to gcc-patches in January [2], and the front-end is temporarily hosted in the sourceware forge until integration in GCC is completed [3]. The full language is (almost) already implemented, the compiler is useful and I plan to send official patches for inclusion in GCC 16 very soon. In the meanwhile, I would like to have both autoconf and automake support ready to be added upstream once the front-end lands. This WIP seems to work for me: make, make install, make dist, etc. With a Makefile.am like this: ---- bin_PROGRAMS = program godcc_SOURCES = program.a68 ---- But I am not familiar with the Automake internals and it is likely I am missing something and/or doing something wrong. Comments are welcome. A patch adding Algol 68 support to autoconf has been sent to autoconf-patches@. Salud!
