Subject: Fixes for Perl 4.019 on NCR Tower V.3

Organization: Holos Software, Inc.

Here are the fixes needed to make perl 4.019 on the NCR Tower V.3 system.
I have bundled this as a shar file: feed everything below the CUT line
to /bin/sh.

The file hints/ncr_tower.sh fixes several problems.  It replaces the
standard copy thereof.  Note that I use perl's malloc.  Note also
that I have turned the optimizer completely off (-O0).  Optimizing
at -O1 or -O2 produces some errors that the test suite doesn't catch.
(Problems with alloca() and setjmp/longjmp, I think.)  It should be
possible to optimize some modules but I haven't experimented with this.

[NOTE: this hints file is already installed--lwall]

I'm don't know if mkdir(2) works: I've left it undef'ed.  It is certainly
broken in V.2.  If you need fast mkdir's you may want to experiment with
this.

The file patch.twg fixes a stupidity in /usr/netinclude/sys/time.h.
You'll need this if you have WIN-TCP; you can't use it if you don't
have WIN-TCP.  If needed, apply this patch *before* running Configure.

Make sure you tell Configure that any config.sh it finds is to be ignored.

After running Configure and make depend, edit config.h so that
the CPPSTDIN definition has DEFAULT_CPP=/dev/null prepended.  It should
look this this:

#define CPPSTDIN "DEFAULT_CPP=/dev/null cc -E"

This must be done by hand after running "make depend" and before running
make.  I was unable to encode this into the hints file.

This resulting perl should pass all tests.

XThe following patch fixes /usr/netinclude/sys/time.h on the Tower V.3.
XPulling in <sys/time.h> with -I/usr/inetinclude makes a mess unless
Xthe <sys/twg_config.h> file is pulled in, too.  It's stupid that an
Xapplication (e.g., perl) should have to do this.  Thus, I fixed
Xthe system header file.  The alternative is to make each application
Xget the header file itself.  (The #if allows the application to do
Xit, though, for compatibility with existing applications.)
X
XTo apply this patch, chdir to /usr/netinclude/sys and run
X	patch <this_file
X
XIf the patch fails, fix the file by hand.  All I've done is put
X#ifndef HDEF
X	/* Len Reed 5/6/91 -- pulling in <sys/time.h> shouldn't cause
X	   HDEF to blow up the compile--auto pull in its defining file.

X# include <sys/twg_config.h>
