Recent versions of autoconf appear to split a lot of the autconf functionality between autoconf proper and "m4 sugar." I think the idea is that the m4sugar code could be useful for other things, so that why I think they want a second prefix. Personally, I think that second prefix should be something less likely to collide with existing variable (like M4S_, say), and that autoconf should just generate warning about this since it does not know what variables people have used up to this point. In general, I think a number of recent changes in autoconf have broken backward compatability unnecessarily. Nevertheless, autoconf-2.53 is out there. You will probably have to field the same trouble report repeatedly if you do not work around the problem. The workaround is not only very simple; it's also an improvement. ASM_xxxxxxx is more mnemonic than AS_xxxxx and more consistent with other flags related to assember issues in gcc. So, I would still recommend that you apply my patch. Adam J.
