$ test -f /etc/termcap && echo "looks like BSD"

Any single test is likely to confuse software that needs to be portable. 
  This is why, 2 decades ago, the creators of Autoconf popularized the 
practice of testing for individual needed features, not whole platforms.

(You see this in the long output from a "configure" script.  It doesn't 
just say "looks like Linux".)

Cygwin does conform most closely to Linux, but if you write softwares 
that blindly assumes Cygwin *is* Linux, you're likely to get surprised 
at some point.
