These patches to the pd ksh posted some time ago will let you build
it successfully under SunOS 4.1 and above. (I haven't tried 4.0.3,
since I don't run it here anymore.)
They also fix the problem of ksh hanging when you do ^D at the
beginning of the line.
Just cd to the directory containing the pd ksh sources and run this
through patch -p -N.

Notes on the Standard C / POSIX P1003.1 package
! This package contains header files and library routines
! to provide a standard C (ANSI) and POSIX enviroment for portable programs.
! This allows most OS dependcies to be removed from an application,
! making it much more readable, and isolating them in a small,
! standardized library. It has the disadvantage that it only
! works with fairly stock UNIX versions, but a different approach
! will be used for other systems.
! This package supplements the existing libraries and header files
! of a AT&T-derived Unix system (System V and BSD in particular).
! It also provides function prototypes when the compiler supports them,
improving compile-time error checking and improving portability on
! machines where sizeof(int) == sizeof(size_t) == sizeof(void*) does not hold.
! A different approach will be used for the DOS, Atari St, Minix,
! and possibly V7: a complete replacement standard C library will
! be provided as a separate package. This would not be practical
! with BSD or NFS systems because of the conflicts with the host
! stdio and the replacement stdio in libc's getpwent().
Contents:
! stdc/*: The standard C header files and library.
! posix/*: The POSIX header files and library.
! h/*, h/sys/*: Links to the header files in stdc/ and posix/.
! libstdc.a: The standard C library.
! libposix.a: The POSIX emulation library.
! To create the header files and libraries, perform the following
! three steps in the stdc and posix directories:
! One of _BSD, _SYSV, or _V7 should be defined in the Makefile.
! Do "rm stdc/stdio.h", it gets created by make.
! Do "make link" first to set up the links from *.h to ../h.
! Do "make" to create the library.
! Compile applications with -I$STD/h, link them with -L$STD ... -lstdc -lposix.
! Notes on the standard C package
! The files <locale.h>, <assert.h>, and <math.h> don't exist yet.
! Many standard C functions are not implemented yet.
! These include strtol, strtoul, atexit, tempfile(?), etc.
! The string routines are by Henry Spencer.
! Known portability problems include:
! size_t or ptrdiff_t in <stddef.h> may need to be long.
! The method of creating <stdio.h> from /usr/include/stdio.h and stdio.h_std
! may not work on some versions of UNIX.
! Almost definitely not on Xenix, maybe not on merged BSD-SysV systems.
! This package contains a correct version of setvbuf() which
! depends on the contents of FILE in the host stdio.h.
! This will not work if FILE is neither stock System V or BSD.
! You can safely "#if 0" out the body of setvbuf for PD ksh,
! setvbuf is used to decrease the size of buffers to speed up forks.
! Notes on the POSIX package
! Only headers and function required by the PD KornShell are implemented.
! I do not intend to develop this into a full POSIX emulation package.
! You should install Doug Gwyn's <dirent> package if you do not have
! <dirent.h> nor <sys/dir>. If you do have <dirent.h>, unlink h/dirent.h
! (this should be configured automatically by the makefile).

! libstdc.a: The standard C library.

! Building PD Ksh
! ---------------
! First, create the header files and libraries:
! - define _BSD, _SYSV, or _V7 in stdc/Makefile and posix/Makefile
! - rm stdc/stdio.h
! - cd stdc; make
! - cd ../posix; make posix
! Now, type:
!
! - cd ../src; make
!
! The executable will be in src/ksh.
!
! Notes on the standard C package
!
! - The files <locale.h>, <assert.h>, and <math.h> don't exist yet.
! - Many standard C functions are not implemented yet, including
! strtol strtoul atexit tempfile et al.
! - The string routines are by Henry Spencer.
!
! Known Portability Problems
!
! - size_t or ptrdiff_t in <stddef.h> may need to be long.
! - some versions of Unix may scream when make stdc tries to create a
! stdio.h from /usr/include/stdio.h and stdc/stdio.h_std .. if this
! is the case (e.g. on Xenix and some BSD/SysV mixes), you can do it
! by hand by simply doing:
! cd stdc
! cp stdio.h_std stdio.h
! edit the new stdio.h and insert /usr/include/stdio.h between the lines
! /* system stdio.h goes here ... %%% */
! and
! /* ... end system stdio.h */
!
! - FILE must be in the host stdio.h for setvbuf() to work; also it
! has to be stock System V or BSD, or it'll fail
! - You can safely "#if 0" out the body of setvbuf for PD ksh, setvbuf
! is used to decrease the size of buffers to speed up forks.
! - If the offsetof macro makes your build fail, define BAD_OFFSET in
! the CFLAGS variable in src/Makefile, as such:
! CFLAGS= blahblahblah -DBAD_OFFSET
! - Also previous versions would crash if you did a Ctrl-D (EOF) on
! the line by itself (at least on Suns); this has been fixed (at
! least on Suns :-)).
!
! Notes on the POSIX package
!
! - Only headers and function required by the PD KornShell are
! implemented. I do not intend to develop this into a full POSIX
! emulation package.
! - You should install Doug Gwyn's <dirent> package if you do not have
! <dirent.h> nor <sys/dir>. If you do have <dirent.h>, unlink
! h/dirent.h (this should be configured automatically by the
! makefile).
