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...]

1830 This installation shell script will examine your system and ask you questions
1831 to determine how the perl5 package should be installed. If you get
1832 stuck on a question, you may use a ! shell escape to start a subshell or
1833 execute a command. Many of the questions will have default answers in square
1834 brackets; typing carriage return will give you the default.
1836 On some of the questions which ask for file or directory names you are allowed
1837 to use the ~name construct to specify the login directory belonging to "name",
1838 even if you don't have a shell which knows about that. Questions where this is
1839 allowed will be marked "(~name ok)".
1843 dflt='Type carriage return to continue'
1847 The prompter used in this script allows you to use shell variables and
1848 backticks in your answers. You may use $1, $2, etc... to refer to the words
1849 in the default answer, as if the default line was a set of arguments given to a
1850 script shell. This means you may also use $* to repeat the whole default line,
1851 so you do not have to re-type everything to add something to the default.
1853 Everytime there is a substitution, you will have to confirm. If there is an
1854 error (e.g. an unmatched backtick), the default answer will remain unchanged
1855 and you will be prompted again.
1857 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1858 the questions and use the computed defaults (or the previous answers if there
1859 was already a config.sh file). Type 'Configure -h' for a list of options.
1860 You may also start interactively and then answer '& -d' at any prompt to turn
1861 on the non-interactive behaviour for the remainder of the execution.
1867 Much effort has been expended to ensure that this shell script will run on any
1868 Unix system. If despite that it blows up on yours, your best bet is to edit
1869 Configure and run it again. If you can't run Configure for some reason,
1870 you'll have to generate a config.sh file by hand. Whatever problems you
1871 have, let me (perlbug@perl.org) know how I blew it.
1873 This installation script affects things in two ways:
1875 1) it may do direct variable substitutions on some of the files included
1877 2) it builds a config.h file for inclusion in C programs. You may edit
1878 any of these files as the need arises after running this script.
1880 If you make a mistake on a question, there is no easy way to back up to it
1881 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1882 files. Configure will offer to let you do this before it runs the SH files.

3054 Your gcc has not been compiled for the exact release of
3055 your operating system ($gccosandvers versus $osname$osvers).
3057 In general it is a good idea to keep gcc synchronized with
3058 the operating system because otherwise serious problems
3059 may ensue when trying to compile software, like Perl.
3061 I'm trying to be optimistic here, though, and will continue.
3062 If later during the configuration and build icky compilation
3063 problems appear (headerfile conflicts being the most common
