           Summary: Preprocessor tries to tokenize code that should be
                    unconditionally skipped
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: preprocessor
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rschiele@uni-mannheim.de
                CC: gcc-bugs@gcc.gnu.org

gcc tries to tokenize code that is wrapped around with #if 0 ... #endif 
 
Try compiling the following code: 
 
#if 0 
" 
#endif 
 
Although the quotes are no valid C token, to my opinion the compiler should not care about it, 
as the section should be completely skipped by the preprocessor. But in fact, the compiler 
teminates by the message 
 
missing terminating " character 
 
gcc 3.4 behaves in a sane way here.
