.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,
|

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'.
