+ # && defined(BAZ) /* comment */ \
+ # etc.
+ # Also, in lines like

+ # This code processes the single-line comments first; it assumes there is
+ # at most one straightforward comment per continued preprocessor line,
+ # replacing each non-empty comment (and its surrounding white space) by a
+ # single space. (sed only has a greedy '*' quantifier, so this doesn't
+ # work right if there are multiple comments per line, and strings can look
+ # like comments to it; both are unlikely in a preprocessor statement.) Any
+ # continuation line is joined, and the process repeated on the enlarged
+ # line as long as there are continuations. At the end, if there are any
+ # comments remaining, they are either completely empty or are like the
+ # first situation. The latter are just deleted by first deleting to the
+ # end of line (including preceding white space) things that start with '/*'
+ # and the next char isn't a '*'; then things that start with '/**', but the
+ # next char isn't a '/'. (Subsequent lines of the comment are irrelevant
+ # and get dropped.) At the end, we unjoin very long lines to avoid
