-# There seem to be a problem with unwinding of exception handling when
-# the binaries are compiled with -flto.  For instance in autfilt,
-# argp_parse() calls the locally defined parse_opt() that calls
-# remove_ap::add_ap() (in libspot).  The latter may throw an
-# exception, which should be caught in main().  However If autfilt is
-# compiled with -flto, the exception never traverses argp.  Moving
-# the try/catch block inside parse_opt() also fixes this praticular
-# problem, but who knows about other exceptions?   So as a workaround,
-# we simply disable -flto in bin/.
