--- Comment #8 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---

Why didn't I think of that for PR ada/100486?  So the fix should have been =
to
add -shared-libgcc to GCC_LINKERFLAGS in gcc/ada/gcc-interface/Make-lang.in:

# Strip -Werror during linking for the LTO bootstrap
GCC_LINKERFLAGS =3D $(filter-out -Werror, $(ALL_LINKERFLAGS)) -shared-libgcc

in your setup since you link gnat1 with shared libraries. This should overr=
ide
the -static-libgcc in ALL_LINKERFLAGS inherited from toplevel.

So you need to to it 1) for GCC 11: rebuild it and reinstall it 2) for GCC =
12:
build it with the patched GCC 11.  Note that this means that GCC 11 is
currently not fully functional anyway.=
