This is my patch patch.1n for perl5.001.perl-5.001n
To apply, change to your perl directory, run the command above, then apply with patch -p1 -N < thispatch. This is a consolidation patch. It contains many of the most commonly applied or agreed-to patches that have been circulating since patch.1m. It also changes the 'unofficial patchlevel' in perl.c. There are some problems (see items marked with '***'). I will attempt to address those in a patch.1o in a few days. This patch contains the following packages: My Jumbo Configure patch vs. 1m, with subsequent patches 1, 2, and 3. Mainly, this provides easier use of local libraries, documents the installation process in a new INSTALL file, moves important questions towards the beginning, and improves detection of signal names (mostly for Linux). xsubpp-1.922. Patches from Larry: eval "1" memory leak patch (as modified by GSAR to apply to 5.001m). NETaa14551 Infinite loop in formats, NETaa13729 scope.c patch (fixed problems on AIX and others) NETaa14138 "substr() & s///" (pp_hot.c) Patches from ftp.perl.com: ftp://ftp.perl.com/pub/perl/src/patches/closure-bug.patch, version of 20 Sep 1995 Includes fix for NETaa14347 (32k limit in regex), and other fixes. ftp://ftp.perl.com/pub/perl/src/patches/debugger.patch, version of 27 Aug 1995 ftp://ftp.perl.com/pub/perl/src/patches/glob-undef.patch, version of 4 Sep 1995 NETaa14421 $_ doesn't undef ftp://ftp.perl.com/pub/perl/src/patches/op-segfault.patch, version of 21 Aug 1995 ftp://ftp.perl.com/pub/perl/src/patches/warn-ref-hash-key.patch, version of 5 Jun 1995 Tim Bunce's Jumbo DynaLoader patch for Perl5.001m, which is NETaa14636 Jumbo DynaLoader patch for Perl5.001m, and Additional patch for NETaa14636 Jumbo DynaLoader patch for Perl5.001m version of 09 Oct 1995. ***This needs some additional parentheses.*** MakeMaker-5.00. Supercedes NETaa13540 (VMS MakeMaker patches). (Updates minimod.PL as well.) ***This has a couple of minor problems. pod2man is run even if it isn't available. LD_RUN_PATH gets set to some mysterious values.*** NETaa14657 Paul Marquess Net::Ping patch. I've included Net-Ping-1.00. NETaa14661 Dean Roehrich DProf. Installed as ext/Devel/DProf. Configure should pick this up automatically. (5 Apr 1995 version.) NETaa13742 Jack Shirazi Socket in 5.001. I've also included his socket.t test in t/lib/socket.t. c2ph-1.7. Dean's perlapi patches of Oct 12, 1995, which superceded those of Oct 8, 1995. This is the one that did mv perlapi.pid perlxs.pod. NETaa14310 Tim Bunce A trivial patch for configpm (handy for shell scripts) DB_File-1.0 patch from Paul Marquess (pmarquess@bfsec.bt.co.uk) last modified 7th October 1995 version 1.0 Added or updated the following hints files: hints/hpux.sh hints/ncr_tower.sh hints/netbsd.sh hints/ultrix.sh Patch and enjoy.

@@ -19,10 +24,62 @@ file, this uses the B<h2xs> program (see the Perl source distribution)
and your native C compiler. This means that it has a
far more likely chance of getting the numbers right.
-=head1 NOTE
+In addition, some structure manipulation functions are available:
+
+=item inet_aton HOSTNAME
+
+Takes a string giving the name of a host, and translates that
+to the 4-byte string (structure). Takes arguments of both
+the 'rtfm.mit.edu' type and '18.181.0.24'. If the host name
+cannot be resolved, returns undef.
+
+=item inet_ntoa IP_ADDRESS
+
+Takes a four byte ip address (as returned by inet_aton())
+and translates it into a string of the form 'd.d.d.d'
+where the 'd's are numbers less than 256 (the normal
+readable four dotted number notation for internet addresses).
+
+=item INADDR_ANY
+
+Note - does not return a number.
+
+Returns the 4-byte wildcard ip address which specifies any
+of the hosts ip addresses. (A particular machine can have
+more than one ip address, each address corresponding to
+a particular network interface. This wildcard address
+allows you to bind to all of them simultaneously.)
+Normally equivalent to inet_aton('0.0.0.0').
+
+=item INADDR_LOOPBACK
+
+Note - does not return a number.
+
+Returns the 4-byte loopback address. Normally equivalent
+to inet_aton('localhost').
-Only C<#define> symbols get translated; you must still correctly
-pack up your own arguments to pass to bind(), etc.
+=item INADDR_NONE
+
+Note - does not return a number.
+
+Returns the 4-byte invalid ip address. Normally equivalent
+to inet_aton('255.255.255.255').
+
+=item pack_sockaddr_in FAMILY, PORT, IP_ADDRESS
+
+Takes three arguments, an address family (normally AF_INET),
+a port number, and a 4 byte IP_ADDRESS (as returned by
+inet_aton()). Returns the sockaddr_in structure with those
+arguments packed in. For internet domain sockets, this structure
+is normally what you need for the arguments in bind(), connect(),
+and send(), and is also returned by getpeername(), getsockname()
+and recv().
+
+=item unpack_sockaddr_in SOCKADDR_IN
+
+Takes a sockaddr_in structure (as returned by pack_sockaddr_in())
+and returns an array of three elements: the address family,
+the port, and the 4-byte ip-address.
