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...]

1824 This installation shell script will examine your system and ask you questions
1825 to determine how the perl5 package should be installed. If you get
1826 stuck on a question, you may use a ! shell escape to start a subshell or
1827 execute a command. Many of the questions will have default answers in square
1828 brackets; typing carriage return will give you the default.
1830 On some of the questions which ask for file or directory names you are allowed
1831 to use the ~name construct to specify the login directory belonging to "name",
1832 even if you don't have a shell which knows about that. Questions where this is
1833 allowed will be marked "(~name ok)".
1837 dflt='Type carriage return to continue'
1841 The prompter used in this script allows you to use shell variables and
1842 backticks in your answers. You may use $1, $2, etc... to refer to the words
1843 in the default answer, as if the default line was a set of arguments given to a
1844 script shell. This means you may also use $* to repeat the whole default line,
1845 so you do not have to re-type everything to add something to the default.
1847 Everytime there is a substitution, you will have to confirm. If there is an
1848 error (e.g. an unmatched backtick), the default answer will remain unchanged
1849 and you will be prompted again.
1851 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1852 the questions and use the computed defaults (or the previous answers if there
1853 was already a config.sh file). Type 'Configure -h' for a list of options.
1854 You may also start interactively and then answer '& -d' at any prompt to turn
1855 on the non-interactive behaviour for the remainder of the execution.
1861 Much effort has been expended to ensure that this shell script will run on any
1862 Unix system. If despite that it blows up on yours, your best bet is to edit
1863 Configure and run it again. If you can't run Configure for some reason,
1864 you'll have to generate a config.sh file by hand. Whatever problems you
1865 have, let me (perlbug@perl.com) know how I blew it.
1867 This installation script affects things in two ways:
1869 1) it may do direct variable substitutions on some of the files included
1871 2) it builds a config.h file for inclusion in C programs. You may edit
1872 any of these files as the need arises after running this script.
1874 If you make a mistake on a question, there is no easy way to back up to it
1875 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1876 files. Configure will offer to let you do this before it runs the SH files.

3246 your operating system ($gccosandvers versus $osname$osvers).
3248 In general it is a good idea to keep gcc synchronized with
3249 the operating system because otherwise serious problems
3250 may ensue when trying to compile software, like Perl.
3252 I'm trying to be optimistic here, though, and will continue.
3253 If later during the configuration and build icky compilation
3254 problems appear (headerfile conflicts being the most common

5114 : see if setuid scripts can be secure
5117 Some kernels have a bug that prevents setuid #! scripts from being
5118 secure. Some sites have disabled setuid #! scripts because of this.
5120 First let's decide if your kernel supports secure setuid #! scripts.
5121 (If setuid #! scripts would be secure but have been disabled anyway,
5122 don't say that they are secure if asked.)
