   6 # (If you are trying to port this package to a machine without sh,
   7 # I would suggest you have a look at the prototypical config_h.SH file
   8 # and edit it to reflect your system. Some packages may include samples
   9 # of config.h for certain machines, so you might look for one of those.)
  10 #
  11 # Yes, you may rip this off to use in other distribution packages. This
  12 # script belongs to the public domain and cannot be copyrighted.
  13 #
  14 # (Note: this Configure script was generated automatically. Rather than
  15 # working with this copy of Configure, you may wish to get metaconfig.
  16 # The dist-3.0 package (which contains metaconfig) was posted in
  17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
  18 # you may fetch it yourself from your nearest archive site.)

2135 so you do not have to re-type everything to add something to the default.
2136
2137 Everytime there is a substitution, you will have to confirm.  If there is an
2138 error (e.g. an unmatched backtick), the default answer will remain unchanged
2139 and you will be prompted again.
2140
2141 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2142 the questions and use the computed defaults (or the previous answers if there
2143 was already a config.sh file). Type 'Configure -h' for a list of options.
2144 You may also start interactively and then answer '& -d' at any prompt to turn
2145 on the non-interactive behaviour for the remainder of the execution.

2151 Much effort has been expended to ensure that this shell script will run on any
2152 Unix system.  If despite that it blows up on yours, your best bet is to edit
2153 Configure and run it again.  If you can't run Configure for some reason,
2154 you'll have to generate a config.sh file by hand.  Whatever problems you
2155 have, let me (perlbug@perl.org) know how I blew it.
2156
2157 This installation script affects things in two ways:
2158
2159 1) it may do direct variable substitutions on some of the files included
2160    in this kit.
2161 2) it builds a config.h file for inclusion in C programs.  You may edit
2162    any of these files as the need arises after running this script.
2163
2164 If you make a mistake on a question, there is no easy way to back up to it
2165 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2166 files.  Configure will offer to let you do this before it runs the SH files.

3888     your operating system ($gccosandvers versus $osname$osvers).
3889
3890     In general it is a good idea to keep gcc synchronized with
3891     the operating system because otherwise serious problems
3892     may ensue when trying to compile software, like Perl.
3893
3894     I'm trying to be optimistic here, though, and will continue.
3895     If later during the configuration and build icky compilation
3896     problems appear (headerfile conflicts being the most common
3897     manifestation), I suggest reinstalling the gcc to match
3898     your operating system release.
