Modified Files: src/usr.bin/make: var.c src/usr.bin/make/unit-tests: cond-func-empty.mk counter-append.exp counter-append.mk counter.exp counter.mk Log Message: make(1): fix unexpected behavior in ::= variable modifier Previously, the ::= modifier had returned an error value, which caused the variable expression to be preserved. This behavior was not useful in this case; it had only been intended to be used for undefined variables. To fix it, distinguish between parse errors, undefined variables and regular empty strings.
