Big caveat: don't know if the standard VM source tree has changed 
significantly in the last month or so.  Using the same source tree that 
I have for about a month (generated with VMMaker from 3.7 and with a 
platform tree from Sourceforge), I found one small issue while building 
the VM on Panther with Xcode.

Xcode automatically upgrades Project Builder projects, so I had it 
upgrade the project I had already tweaked from original sources that 
had always worked fine.  Started a clean and then a build, things went 
fine.  Only error was in "Squeak VM.r," a resource file where Xcode 
complained that it "can't find resource 'hfdr'."  Odd, 'cause it looks 
like a standard resource type that *should* be included (for 
completeness).

Anyway, removing the "resource 'hfdr'" directive from the offending 
file allowed the build to complete with success and the VM runs as 
before.

Anybody have any guesses whether something has changed regarding what 
Apple expects developers to do when building for Panther?  Perhaps 
something needs to be made explicit that our projects have always 
assumed was implicit.

Otherwise, works fine.
