Yeah, sure, but IMHO it's: - still less confusing than what we have now - not that confusing if documented from the beginning, as it's local to $(shell) - could even be useful, not to care about unneeded expansions > I don't think I want it to work that way. Well, then $(setenv TEST,something else) (suggested in the bug-tracker) looks good on multiple points, provided it neither defines nor changes 'TEST' make variable. -- Sergey _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
