That's rather contentious. We've both recently contributed to hc11.

Most of the addition by volume was from me. The code you have
contributed was to support linking in of the xgate additional target you
added.

(We discussed your other patch by email.) I'm still not sure I can think
of a case where a symbol would be created in XGATE space that needs to
be referenced by the S12, but the check you've added for that case is
likely harmless.

However, it would be worth adding some testcases to the testsuite to
confirm the new behaviour.
