If you are just trying to figure out if you're running as cygwin or
linux there are many ways to do this. You already mentioned that linux
won't have a /cygdrive. That could be a key.
Otherwise, the standard way to check this is using uname -s.
If you are trying to figure out from the server side if the system is
running linux or cygwin then the existence of /cygdrive should do it.
