HUGE was undefined but compiled without complaint on both iMac-2013 and GNU Linux. Never noticed it. (i hope gcc doesn't define it, glibc does not). For the time being it is EPSILON until I know a exactly the value which would cause (NaN).
You are right: in GNU Linux using gcc-10.2.0 multiple definitions error are thrown but NOT IN gcc-4.7.4. You should know that this is due to UBUNTU changing -fno-common -fcommon defaults not due to source code. It is an RH+UBUNTU or your error in not setting up libc /usr/include options to compile code of the period. (while I don't like it, having multiple of every compiler on hand is the "plan" of RH+UBU). It now compiles on both.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Those examples from the old FTP site I cannot say if they all should work. I can say in the "ftp-web" tarball there is a directory with the "web page" version of documentation which is nice to read in addition to the pdf. It is no longer online anywhere.
buckyball.ray works if you edit line 2 "sample" to "samples".
For aquarium.ray I hadn't got to work when I tried a few years ago. For fun I tried it today. If "fish" named object and another line commented out it works (seeing file after cpp -P). Turns out: edit original aquarium.ray and change "stripe" to "striped". Now it will work. Converted from rle to jpg viewed in xli, looks good. Probably a conflict with a built-in name - I am not sure didn't check.
There was a change from "version 1" to "version 2" for .ray syntax. program "rsconvert" corrects. I cannot say if that would revive the fish or not.
You can look at ray4mm.tar.gz (for Mathematica) which has a ~/rayshade/extra which has RSDEFS setup. (RSDEFS defines many extras like 3D TEXT and has a couple nice examples). defs.rh needs to be edited #define RSDEFS ~/rayshade/extra or it will get an error.

I'm trying to compile Rayshade from this repo as I failed to compile the one from Stanford, but it's giving me all sorts of errors:
fogdeck.c : 'HUGE' undefined
lex.o: multiple definition of 'yyin'
lex.o: multiple definition of 'yyout'
lex.o: multiple definition of 'yylineno'
How do I fix these errors?
FIXED.
Thank you.

Now it's compiling fine, thanks.
Most of the example files aren't rendering though:
