I don't think Lars used the right term when he said Carbon. Carbon.framework
definitely is non-working in 64-bit mode:
$ objdump -f /System/Library/Frameworks/Carbon.framework/Carbon
/System/Library/Frameworks/Carbon.framework/Carbon: file format Mach-O 64-
XcodeDefault.xctoolchain/usr/bin/objdump: error: '/System/Library/Frameworks/
Carbon.framework/Carbon': Invalid/Unsupported object file format.
What he meant is that Qt uses a number of C APIs even in 64-bit mode that used
to be loosely called "Carbon" back in the day, opposing to the Objective C
APIs called "Cocoa". Example: CoreFoundation.
