No, the uname on FreeBSD returns "FreeBSD" and the uname on Mac OS X returns
"Darwin". The version identifiers are lower-cased for all of the systems, with
the common pre-defined definition in GDC being version(Unix) which matches
version(Windows). Unfortunately, DMD is missing "Unix" and only has "linux".

Why would you need this ? It's built-in anyway... But it's used for Makefile
inclusions in wxD, for instance. So it comes in handy once in a while. The
definitions for MinGW and Cygwin are rather ugly, though. (includes version and
is upper-case, looks something like "MINGW32_NT-5.1" or "CYGWIN_NT-5.1")


Anyway, the whole issue was brought up years ago (2005) and should be a
WONTFIX. See for instance
