Managed to spend a few hours building a VM under Xcode 2.0 and GCC 4.x.
I've posted a set of changes under the 3.8.8b3 series (unreleased) to get the VM to compile without too many warnings. Also I discovered and cross check with other developers that GCC 3.3 with '-fast' still produces the fastest assembler as compared to 4.x which does a lousy job without lots of hints.
GCC 4.x on the other hand flagged a number of errors and pointed out the fetching of volume create dates was wrong. Further checking showed this never worked, and required a bit of tinkering to get the HFS+ 64bit date/time stamps into Squeak epoch date/times.
All this plus the project updates have been posted to the SVN server.
