you have the macros of WINDOWS, UNIX, LINUX etc... {$IFDEF WINDOWS} ...

Please note that system.d is Fedora implementation (v15) so for Linux you
need to detect also the Linux distro, and that's a bit more complicated.

/etc/issue Can help, but also /etc/redhat /etc/debian etc.. can also help
you to figure out what distro it is, but that will work only on specific
distro's as well.
