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...]

1832 This installation shell script will examine your system and ask you questions
1833 to determine how the perl5 package should be installed. If you get
1834 stuck on a question, you may use a ! shell escape to start a subshell or
1835 execute a command. Many of the questions will have default answers in square
1836 brackets; typing carriage return will give you the default.
1838 On some of the questions which ask for file or directory names you are allowed
1839 to use the ~name construct to specify the login directory belonging to "name",
1840 even if you don't have a shell which knows about that. Questions where this is
1841 allowed will be marked "(~name ok)".
1845 dflt='Type carriage return to continue'
1849 The prompter used in this script allows you to use shell variables and
1850 backticks in your answers. You may use $1, $2, etc... to refer to the words
1851 in the default answer, as if the default line was a set of arguments given to a
1852 script shell. This means you may also use $* to repeat the whole default line,
1853 so you do not have to re-type everything to add something to the default.
1855 Everytime there is a substitution, you will have to confirm. If there is an
1856 error (e.g. an unmatched backtick), the default answer will remain unchanged
1857 and you will be prompted again.
1859 If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all
1860 the questions and use the computed defaults (or the previous answers if there
1861 was already a config.sh file). Type 'Configure -h' for a list of options.
1862 You may also start interactively and then answer '& -d' at any prompt to turn
1863 on the non-interactive behaviour for the remainder of the execution.
1869 Much effort has been expended to ensure that this shell script will run on any
1870 Unix system. If despite that it blows up on yours, your best bet is to edit
1871 Configure and run it again. If you can't run Configure for some reason,
1872 you'll have to generate a config.sh file by hand. Whatever problems you
1873 have, let me (perlbug@perl.org) know how I blew it.
1875 This installation script affects things in two ways:
1877 1) it may do direct variable substitutions on some of the files included
1879 2) it builds a config.h file for inclusion in C programs. You may edit
1880 any of these files as the need arises after running this script.
1882 If you make a mistake on a question, there is no easy way to back up to it
1883 currently. The easiest thing to do is to edit config.sh and rerun all the SH
1884 files. Configure will offer to let you do this before it runs the SH files.

3258 your operating system ($gccosandvers versus $osname$osvers).
3260 In general it is a good idea to keep gcc synchronized with
3261 the operating system because otherwise serious problems
3262 may ensue when trying to compile software, like Perl.
3264 I'm trying to be optimistic here, though, and will continue.
3265 If later during the configuration and build icky compilation
3266 problems appear (headerfile conflicts being the most common
