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...]

1827 This installation shell script will examine your system and ask you questions
1828 to determine how the perl5 package should be installed. If you get
1829 stuck on a question, you may use a ! shell escape to start a subshell or
1830 execute a command. Many of the questions will have default answers in square
1831 brackets; typing carriage return will give you the default.
1833 On some of the questions which ask for file or directory names you are allowed
1834 to use the ~name construct to specify the login directory belonging to "name",
1835 even if you don't have a shell which knows about that. Questions where this is
1836 allowed will be marked "(~name ok)".
1840 dflt='Type carriage return to continue'
1844 The prompter used in this script allows you to use shell variables and
1845 backticks in your answers. You may use $1, $2, etc... to refer to the words
1846 in the default answer, as if the default line was a set of arguments given to a
1847 script shell. This means you may also use $* to repeat the whole default line,
1848 so you do not have to re-type everything to add something to the default.
1850 Everytime there is a substitution, you will have to confirm. If there is an
1851 error (e.g. an unmatched backtick), the default answer will remain unchanged
1852 and you will be prompted again.
1854 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1855 the questions and use the computed defaults (or the previous answers if there
1856 was already a config.sh file). Type 'Configure -h' for a list of options.
1857 You may also start interactively and then answer '& -d' at any prompt to turn
1858 on the non-interactive behaviour for the remainder of the execution.
1864 Much effort has been expended to ensure that this shell script will run on any
1865 Unix system. If despite that it blows up on yours, your best bet is to edit
1866 Configure and run it again. If you can't run Configure for some reason,
1867 you'll have to generate a config.sh file by hand. Whatever problems you
1868 have, let me (perlbug@perl.org) know how I blew it.
1870 This installation script affects things in two ways:
1872 1) it may do direct variable substitutions on some of the files included
1874 2) it builds a config.h file for inclusion in C programs. You may edit
1875 any of these files as the need arises after running this script.
1877 If you make a mistake on a question, there is no easy way to back up to it
1878 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1879 files. Configure will offer to let you do this before it runs the SH files.

3046 Your gcc has not been compiled for the exact release of
3047 your operating system ($gccosandvers versus $osname$osvers).
3049 In general it is a good idea to keep gcc synchronized with
3050 the operating system because otherwise serious problems
3051 may ensue when trying to compile software, like Perl.
3053 I'm trying to be optimistic here, though, and will continue.
3054 If later during the configuration and build icky compilation
3055 problems appear (headerfile conflicts being the most common
