But the other tests look like checking for gnutar... no checking for gtar... no checking for tar... /usr/bin/tar checking for gpatch... no checking for patch... /usr/bin/patch checking for autoreconf... /usr/bin/autoreconf
Can't you say checking for -Qunused-arguments... no You can explain this to me, now, and that helps me, today. But I'm trying to save you from having to explain it to many future GHC devs, and/or save them time in hunting for answers to the same question.
