Problems with YYDEBUG and C++

[Potthoff, Kay]

Hello,

 

I'm not shure if this is really a bug, but I think perhaps some corrective action is preferrable.

 

I tried to compile my bison stuff with the C++ compiler and got an error:

 

    # bison -d -v -t parser.yxx

    # mv y.tab.c parser.cxx

    # c++ -Wall -g -DYYDEBUG=1 -c parser.cxx -I.

 

    y.tab.c: In function `int yyparse()':

    y.tab.c: 388: too many arguments to function `char* getenv()'

 

I have taken a look into the produced sources and have seen that first there is a forward declaration of getenv():

 

    extern char* getenv();

 

but later then getenv() is used with one argument:

 

    ... getenv("YYDEBUG") ...

 

This is ok for a C-compiler but my C++-compiler don't like this. By the way, if I compile with YYDEBUG=0 then the C++-compiler runs without any complains.

 

The version of bison is 1.28, the version of gcc is 3.0.

 

Regards, Kay
