29 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)

32 we'd have to do is go in and swap the && and || tokens, wherever they are.)

1313 This installation shell script will examine your system and ask you questions
1314 to determine how the perl5 package should be installed. If you get
1315 stuck on a question, you may use a ! shell escape to start a subshell or
1316 execute a command. Many of the questions will have default answers in square
1317 brackets; typing carriage return will give you the default.
1319 On some of the questions which ask for file or directory names you are allowed
1320 to use the ~name construct to specify the login directory belonging to "name",
1321 even if you don't have a shell which knows about that. Questions where this is
1322 allowed will be marked "(~name ok)".
1326 dflt='Type carriage return to continue'
1330 The prompter used in this script allows you to use shell variables and
1331 backticks in your answers. You may use $1, $2, etc... to refer to the words
1332 in the default answer, as if the default line was a set of arguments given to a
1333 script shell. This means you may also use $* to repeat the whole default line,
1334 so you do not have to re-type everything to add something to the default.
1336 Everytime there is a substitution, you will have to confirm. If there is an
1337 error (e.g. an unmatched backtick), the default answer will remain unchanged
1338 and you will be prompted again.
1340 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1341 the questions and use the computed defaults (or the previous answers if there
1342 was already a config.sh file). Type 'Configure -h' for a list of options.
1343 You may also start interactively and then answer '& -d' at any prompt to turn
1344 on the non-interactive behaviour for the remaining of the execution.
1350 Much effort has been expended to ensure that this shell script will run on any
1351 Unix system. If despite that it blows up on yours, your best bet is to edit
1352 Configure and run it again. If you can't run Configure for some reason,
1353 you'll have to generate a config.sh file by hand. Whatever problems you
1354 have, let me (chip@atlantic.net) know how I blew it.
1356 This installation script affects things in two ways:
1358 1) it may do direct variable substitutions on some of the files included
1360 2) it builds a config.h file for inclusion in C programs. You may edit
1361 any of these files as the need arises after running this script.
1363 If you make a mistake on a question, there is no easy way to back up to it
1364 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1365 files. Configure will offer to let you do this before it runs the SH files.

2552 Perl 5.004 can be compiled for binary compatibility with 5.003.
2553 If you decide to do so, you will be able to continue using any
2554 extensions that were compiled for Perl 5.003. However, binary
2555 compatibility forces Perl to expose some of its internal symbols
2556 in the same way that 5.003 did. So you may have symbol conflicts
2557 if you embed a binary-compatible Perl in other programs.

4632 I need to select a good name for the shared libperl. If your system uses
4633 library names with major and minor numbers, then you might want something
4634 like $majmin. Alternatively, if your system uses a single version
4635 number for shared libraries, then you might want to use $majonly.
4636 Or, your system might be quite happy with a simple libperl.$so.
4638 Since the shared libperl will get installed into a version-specific
4639 architecture-dependent directory, the version number of the shared perl
4640 library probably isn't important, so the default should be o.k.
