# History:
# 1.0 (08/10/2012): First public version, supports Xcode up to version 4.6.3
# 1.1 (20/09/2013): Xcode 5 removed llvm-gcc and 10.7 SDK support, grab them from Xcode 3 and 4
# 1.2 (03/02/2014): Xcode 5 broke PPC assembly and linking; fix assembly and grab linker from Xcode 3
# 1.3 (07/10/2014): Xcode 6 removed 10.8 SDK, grab it from Xcode 5.1.1
# 1.4 (21/08/2015): Xcode 7 removed 10.9 and 10.10 SDKs, grab them from Xcode 6.4
# 1.5 (15/10/2015): Fixes for OS X 10.11 El Capitan (nothing can be installed in /usr/bin because of the sandbox)
# 1.6 (11/11/2015): Fix buildpackages, fix /usr/bin/gcc on recent OS X, fix download messages
# 1.7 (05/04/2016): Xcode 7.3 disables support for older SDKs, fix that
# 1.8 (07/04/2016): add options to install only some SDKs or compilers only
# 1.9 (16/09/2016): Xcode 8 dropped 10.11 SDK, get it from Xcode 7.3.1
# 2.0 (02/05/2017): Xcode 8 cannot always link i386 for OS X 10.5, use the Xcode 3 linker for this arch too. Force use of legacy assembler with GCC 4.x.
# 2.1 (17/01/2017): Xcode 9 dropped 10.12 SDK, get it from https://github.com/phracker/MacOSX-SDKs; fix compiling with GNU Ada, and many other fixes
