SkyOS
SkyOS is a privately owned operating system currently in production. SkyOS is mostly POSIX-compliant. It comes with the core of the open source GNU tools, including GCC.
Due to its level of POSIX-compliance and port of the GTK+ widget toolkit, many Linux or other UNIX applications have been ported, including AbiWord and Gaim, as well as a few games, such as Quake.
It was made by Robert Szeleney.
