  Message : tweak make "magic variables" handling The idea is that it's shorter to special-case ${@D} and the likes (two characters variables ending in D or F) instead of having a weird idx encoding. Cons: - this yields an extra "ext" parameter to classify_var Pros: - the weird index encoding vanishes - no need for special treatment if we add more similar variables. - drastically reduces the size of the switch (and the modulo shrinks from 82 to 36) - code will recognize constructs like ${?D} and ${?F}, which puts us in line with FreeBSD and NetBSD bmake, and also with gnu make. from espie
