Additional information

The fix in the 3.11 bugfix branch for i386 and amd64 does not apply to powerpc.

From asmcomp/i386/emit.mlp:

if macosx
&& not !Clflags.output_c_object
&& is_generic_function fundecl.fun_name
then (* #4690 *)
.private_extern {emit_symbol fundecl.fun_name}\n
else
.globl {emit_symbol fundecl.fun_name}\n;

whilst in asmcomp/power/emit.mlp:

if Config.system = "rhapsody" && is_generic_function fundecl.fun_name
then (* #4690 *)
.private_extern {emit_symbol fundecl.fun_name}\n
else
