 *
 * $Log: unistd.h,v $
 * Revision 1.5  2005/04/19 15:46:45  freckle
 * added #include <compiler.h> as the implicit ordering is not sufficient
 * on our red hat machines and the cruisecontrol build fails
 *
 * Revision 1.4  2005/03/24 14:32:02  freckle
 * added creation of include/unistd_orig.h to configure
 * Added NUT_ wrapper for nut's unistd.h functions. Use <unistd_orig.h>
 * instead of "/usr/include/unistd.h". Relevant for unix emulation only.
 *
 * Revision 1.3  2005/02/23 13:42:28  freckle
 * Correctly include /usr/include/unistd.h for unix emulation
 *
 * Revision 1.2  2005/02/21 11:08:45  olereinhardt
 * For unix plattforms I added #include "/usr/include/unistd.h" since some
 * functions needed for unix_nutinit.c are missing in this file...
