** CVS Log
** $Log: dcompat.h,v $
** Revision 1.26  2010-12-01 08:26:10  joergr
** Added OFFIS copyright header (beginning with the year 1994).
**
** Revision 1.25  2010-10-14 13:17:22  joergr
** Updated copyright header. Added reference to COPYRIGHT file.
**
** Revision 1.24  2010-01-20 13:49:47  uli
** Added OFStandard::getProcessID().
**
** Revision 1.23  2005-12-08 16:02:19  meichel
** Changed include path schema for all DCMTK header files
**
** Revision 1.22  2004/08/03 11:42:43  meichel
** Headers libc.h and unistd.h are now included via ofstdinc.h
**
** Revision 1.21  2003/12/17 16:33:26  meichel
** Removed unused macros
**
** Revision 1.20  2003/06/06 09:44:56  meichel
** Added static sleep function in class OFStandard. This replaces the various
**   calls to sleep(), Sleep() and usleep() throughout the toolkit.
**
** Revision 1.19  2002/11/27 13:04:35  meichel
** Adapted module dcmnet to use of new header file ofstdinc.h
**
** Revision 1.18  2000/11/10 16:25:01  meichel
** Fixed problem with DIMSE routines which attempted to delete /dev/null
**   under certain circumstances, which could lead to disastrous results if
**   tools were run with root permissions (what they shouldn't).
**
** Revision 1.17  2000/02/23 15:12:24  meichel
** Corrected macro for Borland C++ Builder 4 workaround.
**
** Revision 1.16  2000/02/01 10:24:06  meichel
** Avoiding to include <stdlib.h> as extern "C" on Borland C++ Builder 4,

** Revision 1.15  1999/11/12 16:51:02  meichel
** Corrected file locking code that did not work correctly under Win95/98.
**
** Revision 1.14  1999/05/04 12:18:04  joergr
** Minor changes to support Cygwin B20.1 (check __CYGWIN__ to distinguish from
** MSVC which also defines _WIN32).
**
** Revision 1.13  1999/04/30 16:36:32  meichel
** Renamed all flock calls to dcmtk_flock to avoid name clash between flock()
** emulation based on fcntl() and a constructor for struct flock.
**
** Revision 1.12  1999/04/21 13:02:56  meichel
** Now always including <windows.h> instead of <winsock.h> on Win32 platforms.
**   This makes sure that <winsock2.h> is used if available.
**
** Revision 1.11  1999/04/19 08:42:35  meichel
** Added constants for access() on Win32.
**
** Revision 1.10  1997/09/11 16:02:15  hewett
** Conditionally included more standard header files into the
** the dcmnet compatibility header file to allow appropriate
** declarations to be picked up.  For Signus GnuWin32.
**
** Revision 1.9  1997/04/18 08:37:30  andreas
** - Removed double include of sys/select
**
** Revision 1.8  1997/02/06 12:14:42  hewett

**
** Revision 1.6  1996/09/27 08:27:59  hewett
** Move the defines for BEGIN_EXTERN_C/END_EXTERN_C to config/include/osconfig.h
** Added support for Win32 by conditionally including <WINSOCK.h>.
**
** Revision 1.5  1996/09/24 16:22:36  hewett
** Added preliminary support for the Macintosh environment (GUSI library).
**
** Revision 1.4  1996/06/20 07:31:09  hewett
