        !             5: 
        !             6: o build gwin-dir-lib from usenet - but since Coherent already has a
        !             7:   header called dirent.h in /usr/include, change the new header to the other
        !             8:   common name for it, ndir.h;  also add a new header called dirent.h to
        !             9:   /usr/include/sys.  The new routines were put in /usr/lib/libdir.a so LDFLAGS
        !            10:   in Makefile got defined to -ldir and LDFLAGS was added to the compilation
        !            11:   rule.
        !            12: 
        !            13: o change  #include <dirent.h>  to  #include <ndir.h> (pax.h)

        !            22:   #if defined __STDC__)
        !            23:   because argument lists are checked when this conditional succeeds but
        !            24:   __STDC__ is defined to be 0 by mwc cc;  similarly for #ifndef __STDC__
        !            25: 
        !            26: o config.h - various mods that get rid of double comments

        !            37: o *.c header names were changed or includes were commented out, e.g.:
        !            38:     <sys/errno.h> -> <errno.h>
        !            39:     <memory.h> was not included; the needed declarations are in <string.h>
        !            40: 
        !            41: o printf format strings referring to asb->sb_size in tar_entry() in list.c
        !            42:   had format changed from %d to %ld
        !            43: 
        !            44: o Because COHERNT "open" is V7 "open" were made changes in the files
        !            45:   buffer.c, fileio.c, paxdir.c, ttyio.c, & opendir.
        !            46: 
        !            47: o pax.c - added message TAR(v7) for old tapes archive.
        !            48: 
        !            49: o In append.c was added lseek(archivefd, -((OFFSET) blocksize), 1). It was
        !            50:   done because ustar started write in the file one block later than 
        !            51:   had to started in the append case.
        !            52: 
        !            53: o ustar does not work with 'u' option. According to this was deleted all
        !            54:   stuff that had any relation to 'u'. From "pax.c" - "short    newer",
        !            55:   from "tar.c" - "case u", 'u' from taropt's option string, f_newer from
        !            56:   check command line, and prompt from "usage()".
        !            57: 
        !            58: o ustar.c
        !            59:   ustar had default blocking factor for extract 20 bl. This number was
        !            60:   in "#define DEF_BLOCKING 20". Now it is "define DEF_BLOCKING 1".
        !            61:  
        !            62: o ustar, pax, & cpio want have a big stack for working with directory
        !            63:   tree. I think that "fixstack +2000 ustar" could help them. 
        !            64: 
        !            65: o for distinguish between COHERENT "tar" and new "tar" the name for new
        !            66:   was changed to "ustar". For this was replacemented "tar" to "ustar"

        !           109:   This program keeps file's names in the data segment. When total number of 
        !           110:   names is big enough, it cannot allocate memory for new directory's entries.
        !           111:   Problem is similar to trouble with "unmkfs". 
        !           112:   "ustar" (pax, cpio) could create archives about 1.7 - 2 Mb.
