make: *** [shp2img] Error 1

[William Kyngesburye]

Sorry I didn't get back to you yesterday Matt.

I just tried it myself - cleaned the source I had successfully built  
back in August, and indeed I'm getting the Unwind_Resume error.

As far as changes to C++ versions - there is the Xcode 2.2 update  
that updated GCC to 4.0.1, but it looks like it's still the same  
version of libstdc++.  This is from Nov 10.  At least for me,  
everything else was built with GCC 4.0.0 from Xcode 2.1, then just  
now MapServer with GCC 4.0.1.
