Of the 562 "checking" lines when running configure on master, 146 of them are "checking whether C compiler handles -W*". This is excessively time consuming. Can gnulib not do less work to acheive this end, or do the work more efficiently ?
Yes, it probably could, but it'd take some hacking to get it to work right. So far, nobody has volunteered to do that. It'd be nontrivial, as the configure-time code needs to work with older GCCs and with compilers other than GCC.
