--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
As of 2026-01-20, bootstrap with Algol68 included FAILs when using boehm-gc
7.6.0:
libga68/ga68-alloc.c: In function ‘_libga68_init_heap’:
libga68/ga68-alloc.c:51:8: error: implicit declaration of function
‘GC_is_init_called’; did you mean ‘GC_is_disabled’?
[-Wimplicit-function-declaration]
   51 |   if (!GC_is_init_called ())
      |        ^~~~~~~~~~~~~~~~~
      |        GC_is_disabled

If libga68 requires a newer version to build, this should at least be
documented in install.texi.
