I ran a script overnight on my laptop (OSX 10.6.4, 2.5GHz Core 2 Duo, 4G, XCode 3.2.5) which does a clean build before and after each of these forward declaration patches (an initial warm-up build was thrown away).

While completely unscientific (only one build at each), it suggests each of these patches trimmed 3-5% from the build time. Accounting for regression in between the patches, the build is about 7% faster after the 4th patch than before the first.

IMO, it seems to be worthwhile to continue forward declaration patches.
