The following reply was made to PR preprocessor/6848; it has been noted by GNATS.

 Sorry, I missed that but the problem still persists.
 
 Try without the "'":
 #define SYMBOL // line 1
 SYMBOL #error Im not a preprocessing directive // line 2
 
 
 
 By the way, I could not find any information describing how replies to 
 bug reports (e-mails) works thus I removed some of the listed e-mail 
 addresses.

Synopsis: Not a preprocessing directive

State-Changed-From-To: feedback->closed
State-Changed-By: neil
State-Changed-When: Wed May 29 12:32:46 2002
State-Changed-Why:
    There is no bug; it is not being treated as a preprocessing
    directive.  What makes you think it is?
    
    The tokens are output as-is into the output stream, like
    any "normal" preprocessor tokens are.  The output stream
    therefore contains
    
    #error I'm not a preprocessing directive
    
    but note that if you check the return value of GCC -E in
    the shell, it is zero, and no error occurred.
    
    If you compile with -c, you of course get a syntax error
    when the compiler proper reads the raw '#'.

>Description:
Line 2 should not be parsed as a preprocessing directive (at least when using -std=iso9899:1999). I have not checked what other language specifications than ISO/IEC 9899:1999 say.

Same problem for "gcc -E".

#define SYMBOL // line 1
SYMBOL #error I'm not a preprocessing directive // line 2
