Then I have a question about compiler warnings. Compiling gdl with our

gcc flags gives a lot of warnings about unused parameters (they are

unused params in callback functions, so the warnings don't really

apply here). Is there an easy way to suppress them just for this

directory using the current build system? There's a trick mentioned in

configure.ac:684 that suggest that removing the parameter name would

fix this, but I'm getting an "error: parameter name omitted" when

trying it? Is it perhaps valid C++, but invalid C?

I believe that the portable and C / C++ way to do it is to just reference the parameter

void foo ( int bar )
