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...]

1816 This installation shell script will examine your system and ask you questions
1817 to determine how the perl5 package should be installed. If you get
1818 stuck on a question, you may use a ! shell escape to start a subshell or
1819 execute a command. Many of the questions will have default answers in square
1820 brackets; typing carriage return will give you the default.
1822 On some of the questions which ask for file or directory names you are allowed
1823 to use the ~name construct to specify the login directory belonging to "name",
1824 even if you don't have a shell which knows about that. Questions where this is
1825 allowed will be marked "(~name ok)".
1829 dflt='Type carriage return to continue'
1833 The prompter used in this script allows you to use shell variables and
1834 backticks in your answers. You may use $1, $2, etc... to refer to the words
1835 in the default answer, as if the default line was a set of arguments given to a
1836 script shell. This means you may also use $* to repeat the whole default line,
1837 so you do not have to re-type everything to add something to the default.
1839 Everytime there is a substitution, you will have to confirm. If there is an
1840 error (e.g. an unmatched backtick), the default answer will remain unchanged
1841 and you will be prompted again.
1843 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1844 the questions and use the computed defaults (or the previous answers if there
1845 was already a config.sh file). Type 'Configure -h' for a list of options.
1846 You may also start interactively and then answer '& -d' at any prompt to turn
1847 on the non-interactive behaviour for the remainder of the execution.
1853 Much effort has been expended to ensure that this shell script will run on any
1854 Unix system. If despite that it blows up on yours, your best bet is to edit
1855 Configure and run it again. If you can't run Configure for some reason,
1856 you'll have to generate a config.sh file by hand. Whatever problems you
1857 have, let me (perlbug@perl.com) know how I blew it.
1859 This installation script affects things in two ways:
1861 1) it may do direct variable substitutions on some of the files included
1863 2) it builds a config.h file for inclusion in C programs. You may edit
1864 any of these files as the need arises after running this script.
1866 If you make a mistake on a question, there is no easy way to back up to it
1867 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1868 files. Configure will offer to let you do this before it runs the SH files.

3238 your operating system ($gccosandvers versus $osname$osvers).

3241 the operating system because otherwise serious problems
3242 may ensue when trying to compile software, like Perl.
3244 I'm trying to be optimistic here, though, and will continue.
3245 If later during the configuration and build icky compilation
3246 problems appear (headerfile conflicts being the most common

5106 : see if setuid scripts can be secure
5109 Some kernels have a bug that prevents setuid #! scripts from being
5110 secure. Some sites have disabled setuid #! scripts because of this.
5112 First let's decide if your kernel supports secure setuid #! scripts.
5113 (If setuid #! scripts would be secure but have been disabled anyway,
5114 don't say that they are secure if asked.)

5196 useless. It is possible for $package to detect those bits and emulate
5197 setuid/setgid in a secure fashion. This emulation will only work if
