[PATCH] a68: add --enable-algol68-posix-prelude
Mohammad-Reza Nabipoor
mnabipoor@gnu.org
Wed Nov 5 20:47:54 GMT 2025
This configure option controls the inclusion of POSIX prelude in Algol68
runtime. By default it is not included in non-POSIX systems.
Thanks to Pietro Monteiro for demonstrating how to handle unsupported
platforms.
Signed-off-by: Mohammad-Reza Nabipoor <mnabipoor@gnu.org>
libga68/ChangeLog
* configure.ac: Add --enable-algol68-posix-prelude option.
* Makefile.am: Make inclusion of `ga68-posix.c' conditional.
* configure: Regenerate.
* Makefile.in: Likewise.
* config.h.in: Likewise.
gcc/ChangeLog
* configure.ac: Add --enable-algol68-posix-prelude option.
* algol68/a68-parser-prelude.cc: Make POSIX prelude available
conditionally.
* algol68/a68-low-posix.cc: Likewise.
* algol68/a68-low-prelude.cc: Likewise.
* configure: Regenerate.
* config.h.in: Likewise.
* aclocal.m4: Likewise.
