I see on the commandline the above call to gcc (spanned by make). You don't get 
what you see?

I'm not in the position to make this decision, but how about removing that 
transformation? The hardcoded -O2 in the configure script should then be 
eliminated as well.

That's how it looks to me.

Calls to gcc define netbsd and freebsd, respecively (-Dnetbsd or something like 
that). The sourcecode does not really make use of this define. So, same source 
code for either platform.
