Revision 1.10 2004-09-12 15:20:23 peter
* sparc has different values for O_ flags
Revision 1.9 2004/03/04 22:15:16 marco
* UnixType changes. Please report problems to me.
Revision 1.8 2004/02/22 15:00:27 marco
* genfdset word count added. Small fix for libc maxsigsetsize
Revision 1.7 2004/01/31 16:17:38 florian
* removed packed directive from Dir type because it's not properly aligned
and it's never passed to the OS
Revision 1.6 2003/12/31 20:17:06 marco
* sigset size adaption for FPC_USE_LIBC
Revision 1.5 2003/12/02 00:04:34 sg
* Fixed ln2bitmask
Revision 1.4 2003/11/19 10:56:15 marco
* some constants moved from System
Revision 1.3 2003/09/14 20:15:01 marco
* Unix reform stage two. Remove all calls from Unix that exist in Baseunix.
Revision 1.2 2003/05/15 22:50:50 jonas
* the stat type is processor-dependent
* the dev_t tpye is processor dependent. Don't use it in the stat type
however, as that one is also used at a time where dev_t is already
defined as qword
Revision 1.1 2002/12/18 16:43:26 marco
* new unix rtl, linux part.....
Revision 1.1 2002/11/12 14:37:59 marco
* Parts of new unix rtl
