TITLE: Continuation of comments

TITLE: rob@phavl.UUCP (Robt Ransbottom)

//  This is a comment with escaped end of lines \
    in it's midst.  Not intuitive, but seems legal \
    to me.  The ARM says little on preprocessing,  \
    so I assume // comments are handled at the   \
    same stage as /* comments, i.e. Standard C rules. \
\
#define EndOfComment	"Was that parsed correctly?  I need to fix my cpp."

Escaped newlines are supposed to result in concatenated source text
lines before comments are recognized as comments.  Therefore, your
funny-looking comment is all one logical line.  Further, it looks
like the empty line before the #define also has an escaped newline,
which means that the #define is in the same line as the comment and
should not be processed.

Some C++ compilers use a hacked-up old-style C preprocessor, and
don't always get these details right.  If the compiler gets it wrong,
you should complain to the vendor.  In the mean time, avoid constructs
which depend on behavior which your compiler might not support.
