Comment (by gdt):

 I did not see this printed out.  My comment is just from code review.
 That branch could be taken if one constructed a build with compilers other
 than from xcode and hid xcrun.   Perhaps unusual, but if we're checking
 for it (and good to check assumptions one by one), the message might as
 well be right.

 No, the BSD systems (FreeBSD, NetBSD, OpenBSD, Dragonfly, and more forks)
 are definitely not Darwin.   Darwin refers to a system developed by Apple
 which is a combination of Mach and BSD code.  As I understand, fairly
 fuzzily, there is fair bit of FreeBSD code (various), and a fair bit of
 NetBSD code (networking).  In theory Darwin is open source, and it used to
 be possible to build Darwin itself and run it.   OS X (now MacOS) is
 Darwin the base system plus the mac stuff on top.    Which is a long way
 of saying that today, ifdef Darwin is really about MacOS only.
