ARGGGHHHH!!!!!
SCO csh still thinks true is false. Write to SCO today and tell them that next
year Configure ought to "rm /bin/csh" unless they fix their blasted shell. :-)
(Actually, Configure ought to just patch csh in place. Hmm. Hmmmmm. All
we'd have to do is go in and swap the && and || tokens, wherever they are.)
[End of diatribe. We now return you to your regularly scheduled programming...]

OOPS! You naughty creature! You didn't run Configure with sh!
I will attempt to remedy the situation by running sh for you...

-d : use defaults for all answers.
-e : go on without questioning past the production of config.sh.
-f : specify an alternate default configuration file.
-h : print this help message and exit (with an error status).
-r : reuse C symbols value if possible (skips costly nm extraction).
-s : silent mode, only echoes questions and essential information.
-D : define symbol to have some value:
-D symbol symbol gets the value 'define'
-D symbol=value symbol gets the value 'value'
-E : stop at the end of questions, after having produced config.sh.
-K : do not use unless you know what you are doing.
-O : let -D and -U override definitions from loaded configuration file.
-S : perform variable substitutions on all .SH files (can mix with -f)
-U : undefine symbol:
-U symbol symbol gets the value 'undef'
-U symbol= symbol gets completely empty
-A : manipulate symbol after the platform specific hints have been applied:
-A symbol=value append " "value to symbol
-A append:symbol=value append value to symbol
-A define:symbol=value define symbol to have value
-A clear:symbol define symbol to be ''
-A define:symbol define symbol to be 'define'
-A eval:symbol=value define symbol to be eval of value
-A prepend:symbol=value prepend value to symbol
-A undef:symbol define symbol to be 'undef'

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

at what may be a noticeable cost in performance. In particular, if you

the paths derived above.
2) ~username interpretations will be done at run time rather than

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