This won't work because the `str' variable above only gets the last
line output by emacs during a compilation. It will either look like
"Compilation exited abnormally" or "Compilation finished".
I suggest if you really want to treat warnings as errors, you can tell
your compiler to do so. Under gcc, you would pass the -Werror flag
during compilation.
Note, also, that even during successful compilation, you can still do
C-x ` to take you to any warnings that may have occured.
