29 SCO csh still thinks true is false. Write to SCO today and tell them that next
30 year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
32 (Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
33 we'd have to do is go in and swap the && and || tokens, wherever they are.)
35 [End of diatribe. We now return you to your regularly scheduled programming...]

1722 This installation shell script will examine your system and ask you questions
1723 to determine how the perl5 package should be installed. If you get
1724 stuck on a question, you may use a ! shell escape to start a subshell or
1725 execute a command. Many of the questions will have default answers in square
1726 brackets; typing carriage return will give you the default.
1728 On some of the questions which ask for file or directory names you are allowed
1729 to use the ~name construct to specify the login directory belonging to "name",
1730 even if you don't have a shell which knows about that. Questions where this is
1731 allowed will be marked "(~name ok)".
1735 dflt='Type carriage return to continue'
1739 The prompter used in this script allows you to use shell variables and
1740 backticks in your answers. You may use $1, $2, etc... to refer to the words
1741 in the default answer, as if the default line was a set of arguments given to a
1742 script shell. This means you may also use $* to repeat the whole default line,
1743 so you do not have to re-type everything to add something to the default.
1745 Everytime there is a substitution, you will have to confirm. If there is an
1746 error (e.g. an unmatched backtick), the default answer will remain unchanged
1747 and you will be prompted again.
1749 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1750 the questions and use the computed defaults (or the previous answers if there
1751 was already a config.sh file). Type 'Configure -h' for a list of options.
1752 You may also start interactively and then answer '& -d' at any prompt to turn
1753 on the non-interactive behaviour for the remainder of the execution.
1759 Much effort has been expended to ensure that this shell script will run on any
1760 Unix system. If despite that it blows up on yours, your best bet is to edit
1761 Configure and run it again. If you can't run Configure for some reason,
1762 you'll have to generate a config.sh file by hand. Whatever problems you
1763 have, let me (perlbug@perl.com) know how I blew it.
1765 This installation script affects things in two ways:
1767 1) it may do direct variable substitutions on some of the files included
1769 2) it builds a config.h file for inclusion in C programs. You may edit
1770 any of these files as the need arises after running this script.
1772 If you make a mistake on a question, there is no easy way to back up to it
1773 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1774 files. Configure will offer to let you do this before it runs the SH files.

7001 (Your platform doesn't have any specific hints for long doubles.)
7009 Perl can be built to take advantage of long longs which
7010 (if available) may give more range for integer numbers.

7054 Previous version of $package used the standard IO mechanisms as defined
7055 in <stdio.h>. Versions 5.003_02 and later of perl allow alternate IO
7056 mechanisms via a "PerlIO" abstraction, but the stdio mechanism is still
7057 the default. This abstraction layer can use AT&T's sfio (if you already
7058 have sfio installed) or regular stdio. Using PerlIO with sfio may cause
7059 problems with some extension modules. Using PerlIO with stdio is safe,
7060 but it is slower than plain stdio and therefore is not the default.
