It's a bug in your expectations.  "#if 0" is not the same as a glorified
comment marker.  The text it contains must still consist of valid
preprocessor tokens, because it must still remain parsable by the
preprocessor.  Consider for example that "#endif" could occur inside a
backslash-newline-continued string and in that case it is a string
literal and not treated as an #endif by the preprocessor.  So, the
preprocessor has to care about balanced quotes, even in text that it is
discarding.
