Comment (by mmoll@…):

 It's easy enough to fix with something like this:
 {{{
 if {[string match *gcc* ${configure.compiler}]} {
    ...
 }
 }}}
 but -Wno* flags only suppress warnings, right? They shouldn't affect code
 generation, I thought. Are you sure this is the problem? Also, why is this
 assigned to me? Isn't css the maintainer for this port?
