In 2 following postings you should find the rest of the patch to
integrate support for the Sun4, Sun3, Apollo and I386 into the 28sep90
version of Scheme->C.  These tree postings will eventually show up on
gatekeeper.dec.com as MCC-28sep90.patches.  (This will happen when
Joel Bartlett returns from vacation :-)  The rest of this message is
the explanatory text at the beginning of the patch. The second message
is the modified files and the 3rd message contains the new files (in
patch format).

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
What is it?
===========
    This file is an integrated set of patches for the 28sep90 version
    of the Scheme->C system.  These patches add support for the
    Sun4/Sparcstation (SPARC), the Sun3 (SUN3), the Apollo DNx500
    (APOLLO) and DN1000 (PRISM) series, and the the 386 (running ISC
    Unix ?).  Most of this is not new work, I simply integrated all the
    patches that were posted for the 23feb90 version.
    
    I have verified this patch on the following machine/OS combinations:
    
    Sun4 - SunOS 4.0.3
    Sun4 - SunOS 4.1
    Sun3 - SunOS 4.0.3
    Apollo DN3500 - Domain/OS SR10.2
    DECSTATION 5100 - Ultrix T3.1D-0 (Rev. 45) Worksystem X2.2 System #3


How to use it.
==============

    This patch was generated against a fresh, unmodified version of the
    28sep90 release of Scheme->C.  I suggest you start with the original
    tar file and untar it.

    1. cd into the top directory of the distribution.  You should see
       something like this from ls -F:

        CHANGES		README		doc/		scrt/		xlib/
        MIPS		VAX		gnuemacs/	scsc/
        RCS/		cdecl/		makefile	test/

    2. Run the patch file through the patch program, like this ("this"
       assumes the patch file lives in the directory that is the top of
       the distribution):

          patch -p -b ".MCC" <MCC-28sep90.patches

       When patch is done, check to be sure there were no rejections.
       This can be done with the following command:

          find . -name '*.rej' -print

       If there were rejections, find out why and correct them.  If it
       was due to a problem in the patch, please let me know.  (I tried
       the patch on the above machines and it works for me :-)

     3. Edit the top level makefile (./makefile) to fix up the
        definition of SRCDIR at a minimum.  You may also want to change
        the various *DIR, *BIN, and *LIB macros that are appropriate for
        your environment.

     4. Run a "make for<ARCH>" command, where ARCH is one of APOLLO,
        I386, MIPS, PRISM, SPARC, SUN3, TITAN, or VAX.  This will create
        the $(CPUDIR) directory, if it does not exist.  It will then
        create a tree of symbolic links to all the directories and
        necessary files in the distribution.

        [ If you can accept the values for CPUDIR that already exist in
        the makefile, you can just say "make for<ARCH> SRCDIR=$PWD"
        where $PWD has a valid pathname to the currect directory]

     5. cd into $(SRCDIR) which you set in #3 above.

     6. Do a "make port"

     7. Verify the build as in step #4 in the README file.


More comments
=============

     Like I said, very little of this work is original.  I simply took
     all the patches produced for the 23sep90 version and made them
     work.  This involved fixing rejections, adding some new parts to
     the changes and removing some changes because the bug/problem they
     addressed was already fixed in the 28sep90 version.  Here is a list
     of the authors of the original patches:

	SPARC  - rec@arris.com (Roger Critchlow)
	I386   - rec@arris.com (Roger Critchlow)
	SUN3   - Mikael Pettersson <mpe@IDA.LiU.SE>
        APOLLO - Ray Lischner {uunet,decwrl}!mntgfx!lisch or lisch@mentor.com
        PRISM  - Ray Lischner {uunet,decwrl}!mntgfx!lisch or lisch@mentor.com

     I am not able to verify the I386 nor the PRISM version of the
     system.  I don't have access to those kinds of machines.  The I386
     patches seemed to mix conditionals between the 386 and SysV.  It
     would be nice if someone with a 386 and SysV could figure out what
     things are SysV requirements.  There are more SysV problems,
     though.  You should look at the README that originally came with
     Critchlow's SPARC-I386 patches.

     The APOLLO and PRSIM machines don't usually have an assembler.  Ray
     Lischner provided the assembler source and an assembled .o file.  I
     have provided the uuencoded .o file.  You could put the following
     section into the APOLLO makefile header to convert the uuencoded
     file into the .o file:

	apollo.o: apollo.o.uu
		uudecode apollo.o.uu

     There may be problems with the assembler, even if you have it.  The
     assembler we have here at MCC will not take the muls.l or the
     mulu.l instructions.


Conclusion
==========

     I hope you find these changes useful.  If you have any problems
     please let me know.  I appreciate any comments that you might have,
     good or bad.  You can reach me via eckelkamp@mcc.com or
