Re: Re: [Tidy-cvs] tidy/src streamio.c,1.27,1.28

The usual approach is a macro (for compiler not supporting the unused pragma):

#define UNUSED( v )  v = v

int foo( int bar )
{
   UNUSED(bar);
   return 3;
}

This prevents the compiler warning about the unused parameter.

I'm doing this from memory.  The following might also work:

#define UNUSED(v) v
