We've long recognized that we will eventually have to jettison our
reliance on Perl 5's Config module, not just for header detection but
for all of our configuration probes.  But that's a post-1.0 project.

In the meantime, since the OP we have added some functionality to
config/auto/headers.pm to compensate for Config's limitations.  See for
example this comment:

sub _list_extra_headers {
    my $conf = shift;
    # some headers may not be probed-for by perl 5, or might not be
    # properly reflected in %Config (i_fcntl seems to be wrong on my
machine,
    # for instance).

So I wonder whether we need to keep this ticket open at this time.

Thank you very much.
