Yay, thanks again!
Meanwhile, rain1 and I found two bugs. First is not really a bug, debug
printing while parsing \xXX. Do
(with-input-from-file "x00.c" parse-c99)
with x00.c:
char *s = "\x66\x6f\x6f\x20";
see patch attached.
The others is parsing of "\0", see null.c. Instead of a null character
(or possibly literally "\0") we get an ascii 0 (without backslash).
Not sure what we want here, if "\0" passes through literally, the
compiler will need to parse strings again and change those to null?
Greetings,
janneke
