Gareth Rees 56a5573881 Update xcode project for xcode 10.0. ... Xcode 10.0 no longer supports building for IA-32, so the MPS can no longer support building for xci3ll using Xcode. Revise example Scheme interpreter so that it can be compiled even if getopt.h includes unistd.h (as it does on macOS). Copied from Perforce Change: 195090		2018-09-18 15:00:45 +01:00
