Re: bug in scan-skel.l

[Hans Aberg]

The thing is though that if the input stream is opened as text, then 
the local newline should be translated into a single '\n' even before 
the lexer sees it. Is the input file opened as binary?

Hi
I am testing bison 2.0 on cygwin and has found a bug in scan-skel.l. 
This bug causes 122 test cases to fail with the error message:

fatal error: invalid token in skeleton: @output @output_parser_name@
The mistake is in line 50 of scan-skel.l:
yytext[yyleng - 1] = '\0';
Where the programmer did not consider the fact that windoze uses two 
characters to represent end of line. I have no patch ready, but I 
assume the nicest solution would be to add something like this to 
system.h:

#ifdef _WIN32
   #define NUMBER_OF_EOL_CHARACTERS 2
#else
   #define NUMBER_OF_EOL_CHARACTERS 1
#endif
and then modify line 50 in scan-skel.l to:
yytext[yyleng - NUMBER_OF_EOL_CHARACTERS] = '\0';
What to do think? At least it resolves my problem.

Martin
