As reported on the list:
I am seeing a similar problem building harfbuzz 0.9.5 with Apple gcc
4.0.1 on OS X 10.5 Leopard:
hb-ot-layout-common-private.hh:406: error: 'struct
OT::CoverageFormat1::Iter' is private
hb-ot-layout-common-private.hh:646: error: within this context
hb-ot-layout-common-private.hh:500: error: 'struct
OT::CoverageFormat2::Iter' is private
hb-ot-layout-common-private.hh:647: error: within this context
make[4]: *** [libharfbuzz_la-hb-ot-layout.lo] Error 1
Also reported as happening with MSVC 2005.
Uniscribe doesn't. And some fonts abuse this feature to get Indic
shaping working in non-complex applications like Adobe's apps.

Patch from Jonathan Kew.
Part of fixing:
Mozilla Bug 801410 - avoid inserting dotted-circle for run-initial
Unicode combining characters in "simple" scripts such as Latin
https://bugzilla.mozilla.org/show_bug.cgi?id=801410
This sequence: U+120B,U+135F,U+120B with the Nyala font from Win7
exposes a GPOS bug in Uniscribe, in that the positioned mark is wrongly
moved as a result a following kern.
This is the one "failure" in the Ethiopic test suite :-).

The logic for pre-base reordering follows the left matra logic.
We had an exception for Malayalam/Tamil in the left matra repositioning
which was not reflected in pre-base reordering.
Malayalam failures down from 337 to 323.

I typically don't like including generating files in tree. But like to
make an exception for this, since this forms the canonical list of
options one would need to go through when building with alternative
build systems.
Incidentally, this makes it not crash with icu-le-hb anymore...
I'm not smart / stupid enough to spend two more days debugging C++
linking issues, and this is ABI-stable at least.
That's really the logic desired. Except that MONGOLIAN VOWEL SEPARATOR
is not default_ignorable but it really should be. Reported to Unicode.
Based on suggestion from Konstantin Ritt.
To be used for a variety of purposes. We save up to five characters
in each direction. No public API changes, everything is taken care
of already. All clients need to do is to call hb_buffer_add_utf* with
the full text + segment info (or at least some context) instead of
just passing in the segment.
Various operations (hb_buffer_reset, hb_buffer_set_length,
hb_buffer_add*) automatically reset the relevant contexts.
