This is my patch patch.1i for perl5.001.

To apply, change to your perl directory, run the commands above, then
apply with
    patch -p1 -N  < thispatch.

After you apply this patch, I would recommend:
    rm config.sh
    sh Configure [whatever options you use]
    make depend
    make 
    make test

Here are the highlights:
    All pod documentation now installed, along with corresponding man
    pages, if possible (Configure allows you to change this).

    cppstdin no longer points back to the build directory.  This
    necessitated two changes to the test suite:  comp/cpp.t is now a
    front end that punts if cppstdin is not yet available (the old
    perl4 trick doesn't work for perl5).  The  op/misc.t test
    ./perl -P -e 'use POSIX;' has been dropped since I couldn't think
    of an elegant way to bypass it for systems that need the cppstdin
    wrapper.

    Grand autoload patch included (minus the installperl, lib/, and
    ext/ changes).  The lib/ changes are in patch.1g, and the
    ext/ changes are in patch.1h.

    Better detection and use of stdio variants, especially on SVR4.

    Sarathy's consolidated patches (for ties) included.

    New filter stuff included.

    Three patches from Larry (gv.c, toke.c, pp_ctl.c)

Patch and enjoy,

Here's the file-by-file breakdown of what's included:

Changes.Conf
    Document changes in the Configure & build process.

Configure
    Upgrade to metaconfig PL55.

    Add /opt hierarchy to paths searched for programs.

    Tye McQueen's updated std stdio testing.

    Prompting for installation info for perl module pages.

    Add possible SITELIB to include site-specific include directories.
    By default this is disabled, but it seemed a neat idea now that
    the standard perl library is getting so big.

    Check that the compiler chosen exists and actually supports the
    options the user specified.

    Correctly sort multiple shared library version numbers.

    Use a compile & link test for gconvert(), dlopen(), and dlerror().

    Do not include build directory name in cppstdin wrapper.

MANIFEST
    Updated.

Makefile.SH
    Reorganized a bit to support separate install.perl and install.man
    targets to use the new installman script and to accomodate those who
    don't want to install the man pages.

    Organize cleanup of .SH files a little better.

    No longer automatically make the pod/*.man files.  This is done by
    installman only if requested.

    Include additional error messages and info for regenerating the
    automatically maintained header files.

    Add 'minitest' target.

README
    Updated.

README.vms
    Fix perl5-porters subscription info.

config_H
    Updated.

config_h.SH
    Updated.

configpm
    Embedded pod.

configure
    GNU configure-like front end to metaconfig's Configure.
    Only supports a few options.

doio.c
    Updated to use new std stdio testing.

embed.h
    Add new symbols for filtering.

global.sym
    see embed.h.

gv.c
    C<sub method;> patch from lwall.

hints/README.hints
    Updated.

hints/aux.sh
    Updated.

hints/cxux.sh
    Updated.

hints/epix.sh
    New file.

hints/freebsd.sh
    Updated.

hints/irix_4.sh
    Updated.

hints/irix_5.sh
    Updated.

hints/irix_6.sh
    Updated.

hints/linux.sh
    Updated.

hints/powerunix.sh
    Updated.

installman
    New file to install pod/*.pod and lib/*.p(m|od) man pages.

installperl
    Move installation of man pages over to installman script.

    Install pod/*.pod files in $privlib/pod/.

    Preserve timestamps on .a files.

makedepend.SH
    Now includes . and .. in PATH to explicitly find cppstdin wrapper.

opcode.h
opcode.pl
    shmwrite fix.

perl.c
    Changed unofficial patchlevel message.

    Included optional SITELIB directory.

perl.h
    #include <memory.h>

    cryptswitch gone/filters added.

    EUNICE replaced by UNLINK_ALL_VERSIONS.  Only matters for VMS.

perldoc.SH
    New file.

pod/perl.pod
    Describe where modpods are.

pp_ctl.c
    sort bug fix from lwall.

pp_hot.c
    csh glob bug fix from tchrist.

    Sarathy's consolidated "tie" patch for NETaa13753 N 2 trey

pp_sys.c
    Emulate flock with lockf, if possible.

    Use new std stdio unit.

proto.h
    Filters stuff.

    prototype for unlnk() is only needed #if UNLINK_ALL_VERSIONS

sv.c
    Sarathy's consolidated "tie" patch for NETaa13753 N 2 trey

    Sarathy's consolidated patch for nested ties.

    Use new std stdio unit.

t/comp/cpp.aux

    New file.  This only gets called if cppstdin is avaiable.

t/comp/cpp.t
    Calls cpp.aux test only if cppstdin is available.

t/op/misc.t
    Drop
	perl -P -e 'use POSIX;' test.
    it couldn't work on systems without the cppstdin wrapper
    installed, and is usually misleading when it fails anyway.

toke.c
    filter stuff.

    fix for NETaa13798 from lwall.

unixish.h
    undef UNLINK_ALL_VERSIONS since it's irrelevant for unix.

util.c
    s/EUNICE/UNLINK_ALL_VERSIONS/ for the unlnk() function.

vms/config.vms
    VMS updates from Charles Bailey.

    std stdio updates to match changes in perl sources.

    add UNLINK_ALL_VERSIONS constant, but leave it #undef.

vms/ext/MM_VMS.pm
vms/ext/VMS/stdio/stdio.xs
vms/perlvms.pod
vms/vms.c
    VMS updates from Charles Bailey.

x2p/Makefile.SH
    Updated to match man page Configure questions.

    Slight clean-up on .SH targets.

x2p/str.c
    Use new std stdio unit.
