Ruby 0.95

Ruby 0.95 was the first publicly released version of Ruby. It was originally published on December 21, 1995.

This is an attempt to get Ruby 0.95 to compile on a modern version of Linux (32-bit Ubuntu 16.04) using a modern compiler (GCC 5.4).

Why?

Why do it? Mostly because I thought it would make for a fun talk at a Ruby meet-up or conference.
Why Ubuntu 16.04? It's the last version of Ubuntu for which 32-bit images were published
Why 32-bit? 64-bit desktop systems weren't really a thing back in 1995: the first x86-64/AMD64 CPU was released in 2003.
Why Linux in the first place? My normal development computer is a Mac, but macOS/OS X wouldn't be released until 2001.

This has only been tested with Ubuntu 16.04 (with GCC 5.4), but other distros would probably work too.

sudo apt install autoconf bison build-essential flex git

git clone https://github.com/matiaskorhonen/ruby-0.95.git
cd ruby-0.95

Make the destination folders (I'm assuming that you don't want to install this system-wide)

# Note that this is a different directory than the git repo
mkdir -p ~/opt/bin
mkdir -p ~/opt/lib/ruby

./configure --host=i386-unknown-linux --prefix="$HOME/opt"

make

make install

echo 'print "Hello from Ruby 0.95\n"' | $HOME/opt/bin/ruby

It segfaults if you look at it wrong
Many things that you might be used to don't exist (e.g. puts or anything HTTP related)
None of the extensions from ext/ are included because I could get the setup script to stop segfaulting
