[Flex-help] Flex C code can not be compiled in C++

The function isatty() in yy_init_buffer(), a flex generated function, is 
not compatible in C++ and generates an error. I am working on a 
work-around but the issue is that this requires that the generated file 
can not be used as is but must be edited. Is there a work-around for 
this? Is there an option which can select another function instead of 
isatty()?

The isatty() call is isatty( fileno( file ) ) where 'file' is of type 
FILE*. I don't know if this is also an issue.

I'd prefer not to do editing if that is possible.

thanks
