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

+ * 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
