- * Revision 1.7 2002/05/13 10:48:35 tr
- * embedded some source code directly to the header so that no source
- * modules need to be included in the MS Visual C project using the
- * interface, removed all the dependencies to other headers of the `uce'
- * library so that the header can be made public
- *
- * Revision 1.6 2002/04/12 16:22:04 tr
- * Unified Compiling Environment (UCE) replaced `std' library
- *
- * Revision 1.5 2001/07/20 16:33:40 tr
- * moved to `std' library and re-named defines accordingly
- *
- * Revision 1.4 2001/07/10 16:47:18 tronkko
- * revised comments
- *
- * Revision 1.3 2001/01/11 13:16:43 tr
- * using ``uce-machine.h'' for finding out defines such as `FREEBSD'
- *
- * Revision 1.2 2000/10/08 16:00:41 tr
- * copy of FreeBSD man page
- *
- * Revision 1.1 2000/07/10 05:53:16 tr
- * Initial revision
- *
- * Revision 1.2 1998/07/19 18:29:14 tr
- * Added error reporting capabilities and some asserts.
- *
- * Revision 1.1 1998/07/04 16:27:51 tr
- * Initial revision
- *
- *
- * MSVC 1.0 scans automatic dependencies incorrectly when your project
- * contains this very header. The problem is that MSVC cannot handle
- * include directives inside #if..#endif block those are never entered.
- * Since this header ought to compile in many different operating systems,
- * there had to be several conditional blocks that are compiled only in
- * operating systems for what they were designed for. MSVC 1.0 cannot
- * handle inclusion of sys/dir.h in a part that is compiled only in Apollo
- * operating system. To fix the problem you need to insert DIR.H into
- * SYSINCL.DAT located in MSVC\BIN directory and restart visual C++.
- * Consult manuals for more informaton about the problem.
- *
- * Since many UNIX systems have dirent.h we assume to have one also.
- * However, if your UNIX system does not have dirent.h you can download one
- * for example at: http://ftp.uni-mannheim.de/ftp/GNU/dirent/dirent.tar.gz.
- * You can also see if you have one of dirent.h, direct.h, dir.h, ndir.h,
- * sys/dir.h and sys/ndir.h somewhere. Try defining HAVE_DIRENT_H,
- * HAVE_DIRECT_H, HAVE_DIR_H, HAVE_NDIR_H, HAVE_SYS_DIR_H and
- * HAVE_SYS_NDIR_H according to the files found.

- * The dirent structure contains several system dependent fields that

- * While d_name is portable across different systems the actual storage

- * way to find out it at compile time as different systems define the
- * capacity of d_name with different macros and some systems do not define
- * capacity at all (besides actual declaration of the field). If you really

- * it. There are also systems that declare d_name as "char d_name[1]" and
- * then allocate suitable amount of memory at run-time. Thanks to Alain
- * Decamps (Alain.Decamps@advalvas.be) for pointing it out to me.

+ * MSVC 1.0 scans automatic dependencies incorrectly when your project
+ * contains this very header. The problem is that MSVC cannot handle
+ * include directives inside #if..#endif block those are never entered.
+ * Since this header ought to compile in many different operating systems,
+ * there had to be several conditional blocks that are compiled only in
+ * operating systems for what they were designed for. MSVC 1.0 cannot
+ * handle inclusion of sys/dir.h in a part that is compiled only in Apollo
+ * operating system. To fix the problem you need to insert DIR.H into
+ * SYSINCL.DAT located in MSVC\BIN directory and restart visual C++.
+ * Consult manuals for more informaton about the problem.
+ *
+ * Since many UNIX systems have dirent.h we assume to have one also.
+ * However, if your UNIX system does not have dirent.h you can download one
+ * for example at: http://ftp.uni-mannheim.de/ftp/GNU/dirent/dirent.tar.gz.
+ * You can also see if you have one of dirent.h, direct.h, dir.h, ndir.h,
+ * sys/dir.h and sys/ndir.h somewhere. Try defining HAVE_DIRENT_H,
+ * HAVE_DIRECT_H, HAVE_DIR_H, HAVE_NDIR_H, HAVE_SYS_DIR_H and
+ * HAVE_SYS_NDIR_H according to the files found.

+ * While d_name is portable across different systems the actual storage
