Thats been a known issue for a long time. The only reason you need to
inherit from DynaLoader is that bootstrap may call the dl_load_flags
method.
The annoying thing is that because you do have AUTOLOAD there then you
get different warnings.
Thats why in the past I have done
{
require DynaLoader;
local @ISA = qw(DynaLoader);
bootstrap List::Util $XS_VERSION;
}
to bootstrap a module.
If the following in DynaLoader.pm was changed from
my $libref = dl_load_file($file, $module->dl_load_flags) or
croak("Can't load '$file' for module $module: ".dl_error());
to
my $dl_load_flags = $module->can('dl_load_flags') ?
$module->dl_load_flags : 0;
my $libref = dl_load_file($file, $dl_load_flags) or
croak("Can't load '$file' for module $module: ".dl_error());
and export bootstrap, there would be no need to inherit from DynaLoader
