I've found -Wattribute and -Werror to be useful with recent GCC. 
However, the cost of pacifying older GCC's warnings typically exceeds 
the benefit.

One possibility is to modify Gnulib to disable -Wattribute in GCC 7 and 
earlier. Another possibility, which I think I might prefer mildly, is 
just to ask people to use the latest version of GCC if they want to 
enable GCC warnings.
