[Sam James found this issue while packaging godcc for Gentoo: https://packages.gentoo.org/packages/dev-util/godcc. Would be nice if we could have this fixed in autoconf 2.73.]
The AC_PROG_A68 macro should honor the A68FLAGS set by the user at configure time. Note that a similar fix may be needed in AC_PROG_GO. I have not fixed that one because it may be intentional there? (unlikely, but just in case.) Signed-off-by: Jose E.
