Building BOINC as a 64 bit application succeeds.

The patch I just attached solves the problem for me. But I am not sure whether it will properly work on earlier versions of Mac OS X.

Building BOINC on a Mac using config and make is not supported. Please use the build scripts and XCode project provided, which work correctly as is. See the file boinc.mac_build/HowToBuildBOINC_XCode.rtf for details. For a more up to date version see here.

Modified the two source files QBacktrace.c and QCrashReport.c so they now build properly using OS OS 10.5 SDk and OS 10.6 SDk as well as OS 10.4 SDK.
