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...]

1835 This installation shell script will examine your system and ask you questions
1836 to determine how the perl5 package should be installed. If you get
1837 stuck on a question, you may use a ! shell escape to start a subshell or
1838 execute a command. Many of the questions will have default answers in square
1839 brackets; typing carriage return will give you the default.
1841 On some of the questions which ask for file or directory names you are allowed
1842 to use the ~name construct to specify the login directory belonging to "name",
1843 even if you don't have a shell which knows about that. Questions where this is
1844 allowed will be marked "(~name ok)".
1848 dflt='Type carriage return to continue'
1852 The prompter used in this script allows you to use shell variables and
1853 backticks in your answers. You may use $1, $2, etc... to refer to the words
1854 in the default answer, as if the default line was a set of arguments given to a
1855 script shell. This means you may also use $* to repeat the whole default line,
1856 so you do not have to re-type everything to add something to the default.
1858 Everytime there is a substitution, you will have to confirm. If there is an
1859 error (e.g. an unmatched backtick), the default answer will remain unchanged
1860 and you will be prompted again.
1862 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1863 the questions and use the computed defaults (or the previous answers if there
1864 was already a config.sh file). Type 'Configure -h' for a list of options.
1865 You may also start interactively and then answer '& -d' at any prompt to turn
1866 on the non-interactive behaviour for the remainder of the execution.
1872 Much effort has been expended to ensure that this shell script will run on any
1873 Unix system. If despite that it blows up on yours, your best bet is to edit
1874 Configure and run it again. If you can't run Configure for some reason,
1875 you'll have to generate a config.sh file by hand. Whatever problems you
1876 have, let me (perlbug@perl.org) know how I blew it.
1878 This installation script affects things in two ways:
1880 1) it may do direct variable substitutions on some of the files included
1882 2) it builds a config.h file for inclusion in C programs. You may edit
1883 any of these files as the need arises after running this script.
1885 If you make a mistake on a question, there is no easy way to back up to it
1886 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1887 files. Configure will offer to let you do this before it runs the SH files.

3064 In general it is a good idea to keep gcc synchronized with
3065 the operating system because otherwise serious problems

3068 I'm trying to be optimistic here, though, and will continue.
3069 If later during the configuration and build icky compilation
