You might enjoy http://canonical.org/~kragen/sw/urscheme/ -- it's by someone who'd just written his first compiler, with links to other sources he found inspiring (one of them mine).
C89 I think has too much complexity for the amount of power it offers. lcc is a nice example: Norman Ramsey said he asked one of the authors what he learned in writing it, and got an answer like "Not to write a compiler in C." But anyway the book about it https://sites.google.com/site/lccretargetablecompiler/ is very good. http://www.cs.princeton.edu/~appel/modern/ is my favorite general text.
