NOTE: Couldn't figure out how to center the text on the X axis (I'm a bit dum)
Here's the example of how the qlock looks

doesn't compile for me:

cc -w -include time.h -o out qlock.c qlock.o -std=c90:

read the comment at the top of the file, please
first you do ld -r -b binary -o qlock.o qlock.c
then you do cc -w -include time.h -o out qlock.c qlock.o

this way linker embeds the source code as text in an object file, which is then used for compilation

my bad for not specifying. I already did the first step before trying to compile.

also, which gcc version are you using? mine only worked with the original code when I specified the -std=c90. also tried compiling your version with multiple C standards

Not sure why You're having some issues, GCC should be able to automatically identify when and what STD version to use

EDIT: i'm an idiot. It should be main.c, not quine.c
I've used main.c as the filename locally, forgot to change the linker reference when i uploaded it to gist

so either rename quine.c to main.c OR change extern char _binary_main_c_start[]; to extern char _binary_quine_c_start[];
