Thanks again for your help Frank. As usual, you were spot on and adding the following line to .../port/cpl_config.h.in before building fixed the problem:
#define HAVE_LONG_LONG 1 I've now added this to my own build notes. Since the problem didn't occur when using the beta versions of Apple's Xcode 5 and only occurred with the final version of Xcode 5, I'm assuming that Apple changed their developer tools/environment with their production release which coincided with their announcement of 64-bit iPhones (iPhone 5S) in such a way that it affected what 'configure' wrote to cpl_config.h.
