--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- And, $gas is not the same thing as $gas_flag. Note, it isn't exactly clear to me where gas variable is set, but clearly in my usual ../configure --enable-languages=default,ada,obj-c++,lto,go,d,m2,cobol,algol68 --enable-checking=yes,rtl,extra --enable-libstdcxx-backtrace=yes configuration HAVE_GNU_AS is defined to 1, so gas has to be yes.
