This behavior is ok. At the GNU C preprocessor info page you can find
the following paragraph:

If backslashes occur within "...", they are considered ordinary text
characters, not escape characters. None of the character escape
sequences appropriate to string constants in C are processed. Thus,
`#include "x\n\\y"' specifies a filename containing three backslashes.
It is not clear why this behavior is ever useful, but the ANSI standard
specifies it.

Exactly :-))

I've designed the preprocessor to behave like this, although I'm also
not really convinced of it. But what should I do, it's standard ;-)

Best regards,
