Unable rather than unwilling?

PGP 8.0.3 and 8.1 definitely did not handle signing subkeys, and
choked if it happened to be the newest subkey.

After trying and not liking PGP 9.x I switched to using GnuPG. I think
it was the UI and the removal of support for encrypting to groups that
prompted the switch, so I can't comment on signing subkey support.
However, Tom McCune [0] says:-

    "GPG began using subkeys for signing before PGP. Until PGP 8.1,
    PGP had no support for this, and could not verify signatures made
    with such a signing subkey. PGP 9.x adds signing subkey
    functioning. With PGP 9.x, you can now generate and use signing
    subkeys - this allows you to continue using your original signing
    key ID and fingerprint for continuity purposes, while being able
    to enhance your signing security with key replacement."
