How do I compile sqlite-1.0.1 that was released 19 years ago?

I'd like to read the SQLite source code and learn how to do it.I'm only interested in the most basic features of DB, and sqlite-1.0.1 has only about 10,000 lines of source code, so I think it's easier to read than sqlite3 applied in many projects now.

Unfortunately, the current gcc does not seem to be able to compile sqlite-1.0.1 from 19 years ago.

wget "https://www.sqlite.org/src/tarball/e8521fc1/SQLite-e8521fc1.tar.gz"
tar xzvf SQLite-e8521fc1.tar.gz
mkdir bld & cd bld
.../SQLite-e8521fc1/configure --prefix=/opt/sqlite-1.0.1 --with-tcl=no
make

The virtual machine installed the old Fedora Core release 3 and tried to compile sqlite-1.0.1 with built-in gcc (gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)), but when running make, the following error message appears: 

gcc-std=c89-g-O2-olemon../SQLite-e8521fc1/tool/lemon.c
Infile included from../SQLite-e8521fc1/tool/lemon.c:29:
/usr/lib/gcc/i386-redhat-linux/3.4.2/include/varargs.h:4:2:# error "GCC no longer implements <vargs.h>."
/usr/lib/gcc/i386-redhat-linux/3.4.2/include/varargs.h:5:2:# error "Revise your code to use<stdarg.h>."

Makefile has tried adding -std=c89 as a parameter for gcc, but cannot compile again

Based on the error message above, gcc version 3.4.2 may be a modern compiler for sqlite-1.0.1.

check in where <vargs.h> has been replaced with <stdarg.h>, and the SQLite author wrote lemon.c to write in 1989 .

Maybe you need to find an older gcc.Where can I get these old things from?What operating systems and compilers did programmers use 19 years ago?
