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...]

1828 This installation shell script will examine your system and ask you questions
1829 to determine how the perl5 package should be installed. If you get
1830 stuck on a question, you may use a ! shell escape to start a subshell or
1831 execute a command. Many of the questions will have default answers in square
1832 brackets; typing carriage return will give you the default.
1834 On some of the questions which ask for file or directory names you are allowed
1835 to use the ~name construct to specify the login directory belonging to "name",
1836 even if you don't have a shell which knows about that. Questions where this is
1837 allowed will be marked "(~name ok)".
1841 dflt='Type carriage return to continue'
1845 The prompter used in this script allows you to use shell variables and
1846 backticks in your answers. You may use $1, $2, etc... to refer to the words
1847 in the default answer, as if the default line was a set of arguments given to a
1848 script shell. This means you may also use $* to repeat the whole default line,
1849 so you do not have to re-type everything to add something to the default.
1851 Everytime there is a substitution, you will have to confirm. If there is an
1852 error (e.g. an unmatched backtick), the default answer will remain unchanged
1853 and you will be prompted again.
1855 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1856 the questions and use the computed defaults (or the previous answers if there
1857 was already a config.sh file). Type 'Configure -h' for a list of options.
1858 You may also start interactively and then answer '& -d' at any prompt to turn
1859 on the non-interactive behaviour for the remainder of the execution.
1865 Much effort has been expended to ensure that this shell script will run on any
1866 Unix system. If despite that it blows up on yours, your best bet is to edit
1867 Configure and run it again. If you can't run Configure for some reason,
1868 you'll have to generate a config.sh file by hand. Whatever problems you
1869 have, let me (perlbug@perl.org) know how I blew it.
1871 This installation script affects things in two ways:
1873 1) it may do direct variable substitutions on some of the files included
1875 2) it builds a config.h file for inclusion in C programs. You may edit
1876 any of these files as the need arises after running this script.
1878 If you make a mistake on a question, there is no easy way to back up to it
1879 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1880 files. Configure will offer to let you do this before it runs the SH files.

3047 Your gcc has not been compiled for the exact release of
3048 your operating system ($gccosandvers versus $osname$osvers).
3050 In general it is a good idea to keep gcc synchronized with
3051 the operating system because otherwise serious problems
3052 may ensue when trying to compile software, like Perl.
3054 I'm trying to be optimistic here, though, and will continue.
3055 If later during the configuration and build icky compilation
3056 problems appear (headerfile conflicts being the most common
