external people regularly ask "but why you don't want to use GNU/m4 GNU/make GNU/whatever ?"
Well, latest one, turns out gnu-m4 has reaaaally sloppy regexp handling. Namely, stuff like regexp(`n', `?') *works* with gm4... I know somewhat incredible... our regexpes obviously will not like ? like that, since it's not a normal character, and gnu regexp handling is such a bluberring piece of code that it works... very reproducible, very so secure. Reminds me of gnu libtool dropping silently stuff it doesn't understand... oh wait, of course, *that* regexp is in the autoconf much leading to gnu libtool. Gee, what a surprise...
