As expected, Algol68 programs FAIL to link when manually providing a
declaration of GC_is_init_called in ga68-alloc.c (so the function isn't
just not declared in <gc/gc.h> in previous versions of libgc).
However, even if I manually disable the LIBGA68_WITH_GC part of
libga68-alloc.c, the library does build and has no undefined references
(except for the expected __algol68_main), but every Algol68 testcase
fails to link:
/vol/gcc/lib/libgc.la: file not recognized: file format not recognized
collect2: error: ld returned 1 exit status
That path is obviously wrong if not linking with libtool, however
libga68.epec includes
%rename lib liborig_ga68_renamed
*lib: %{noga68lib: ; :-lm /vol/gcc/lib/libgc.la} %(liborig_ga68_renamed)
which is clearly wrong. Either provide -lgc instead, maybe with
-L/vol/gcc/lib added. This way, the right lib should be picked up,
with or without libtool.
