Some Makefile issue in 03_Precedence

Hi @ShadowThree! This is just make telling you that it encountered an error. This is expected because when ./parser input03 is executed it encounters an error and returns non-zero, as does ./parser input04 and ./parser input05. Overall, the entire test returns failure, and make is letting you know that. The minus sign in front of the command grouping "-(" is telling it to ignore errors. You see that in the output "...Error 1 (ignored)"

I'm sure Warren removed these from the blog post intentionally to keep the focus on the output of the parser.

Hope this helps.
