It sounds like you are saying that you get the error about
-Wno-overlength-strings when you run "make install".  But running "make
install" should not actually compile anything.  So something has gone
wrong.  Perhaps your timestamps are not right, who knows.

I would recommend running "make" a couple of times until you are sure
that nothing is being recompiled.  Then run "make install".  If it still
fails, show us the last 100 lines or so of make output.
