Sorry to be pedantic, but if you're using a free operating system, which I assume almost all of us here are, you are almost definitely not using a "UNIX"(tm). A high success rate with ./configure; make; make install; does not mean you have a "full-featured UNIX"; more than likely it means you have Linux, which diverges from traditional big iron Unix OSes in some fairly significant ways.
