# Tests for the special .newline variable.
#
# Contrary to the special variable named "" that is used in expressions like
# ${:Usome-value}, the variable ".newline" is not protected against
# modification. Nobody exploits that though.
NEWLINE:= ${.newline}
.newline= overwritten
.if ${.newline} == ${NEWLINE}
.info The .newline variable cannot be overwritten. Good.
.else
.info The .newline variable can be overwritten. Just don't do that.
.endif
# Restore the original value.
.newline= ${NEWLINE}
all:
@echo 'first${.newline}second'
