nm shows that printf gets changed for puts, so after taking everything
out:


int
main(int argc, char *argv[])
{
     printf(¨hello darkness¨);
}

//no includes... no defines, nothing I am paranoid about libc now


gcc -c darkness darkness.c

darkness.c: In function 'main':
darkness.c:5: warning: incompatible implicit declaration of built-in
function 'printf'


wait, builtin??

nm darkness.o

00000000 T main
         U puts

puts?. where did that come from hmm ah builtin...

quoting some anonymous gcc developer
you are not *allowed* to modify the C library
functions unless you ask gcc for permission...

gcc -fno-builtin

gcc -please-let-me-write-my-function-please...
