ioperm for Cygwin adds support for the ioperm()/iopl() functions to Cygwin. This support includes sys/io.h and sys/perm.h header files (not included in Cygwin by default) with development and runtime libraries.

Windows DDK is no longer required to build the ioperm.sys driver. An initial iopl() implementation has been added, and there is an improved look and feel for the ioperm admin tool. The package is now prepared for integration with the mainstream Cygwin net distribution. Minor bugs have been fixed.
