 # Tests for the -W command line option, which turns warnings into errors.

+# Even in -W mode, a .warning is not completely equivalent to an .error.
+# First, the word "warning" is still printed, and second, parsing continues
+# after a failed warning, whereas it would stop immediately at the first
+# .error.
