/*
 * $Log$
 * Revision 1.5  2009/03/05 22:16:57  freckle
 * use __NUT_EMULATION instead of __APPLE__, __linux__, or __CYGWIN__
 *
 * Revision 1.4  2008/08/22 09:25:34  haraldkipp
 * Clock value caching and new functions NutArchClockGet, NutClockGet and
 * NutClockSet added.
 *
 * Revision 1.3  2008/08/11 06:59:58  haraldkipp
 * BSD types replaced by stdint types (feature request #1282721).
 *
 * Revision 1.2  2008/07/08 08:25:05  haraldkipp
 * NutDelay is no more architecture specific.
 * Number of loops per millisecond is configurable or will be automatically
 * determined.
 * A new function NutMicroDelay provides shorter delays.
 *
 * Revision 1.1  2005/07/26 18:42:19  haraldkipp
 * First check in
