 Description  « Hide
character constant early termination (newline, eof) is not handled correctly in the preprocessor, consider the following cases

' foo
foo

' foo<EOF>

' foo\<EOF>

will produce the following outputs

' foo

foo

(spurious newline)

' fooÿ

(0xff character)

' fooÿÿ

(0xff character twice)

the attached patch for token.c corrects these cases

Fixed, thanks for the patch. I also added some code for handling of \\n inside character constants.
