I'm aware that OS X ships ICU libs but not headers, so it's great that WebKit
itself has a copy of those missing files. But why does it need three copies of
those files?

Also, given that ICU is a generally useful thing, users may have ICU from some
other vendor, installed in a more complete fashion (i.e., with headers).Given
that it's an external lib (from perspective of WebKit), why not use it
externally? Worse, if user does have a different ICU version installed, you're
forcing use of headers (via local -I) that may not match the globally available
lib (found via -l, there is no local -L for the lib). Even assuming a vanilla
OS X system, 10.5 and 10.4 have different versions of ICU so half the time (as
of public supported OS X releases:) you're *forcing* use of mismatched headers.
Fink among other vendors can install global headers "that match OS X headerless
lib", so I can be sure I get a matched set.
