# Demonstrate that an inference rule is considered the main target if its
# suffixes are not known at the point of declaration.
.1.2:
: Making ${.TARGET} from ${.IMPSRC}.
# At this point, the target '.1.2' is a normal target.
# Since it is the first target in the first dependency declaration,
# it becomes the main target.
next-main:
: Making ${.TARGET}
# At this point, 'next-main' is effectively ignored.
# Declaring both '.1' and '.2' as suffixes turns the '.1.2' target into an
# inference rule (OP_TRANSFORM). As a side effect, this target is no longer
# a candidate for the main target. Therefore the next target is selected as
# the main target, which in this case is 'next-main'.
