# https://gnats.netbsd.org/49086, issue 10:
# Explicit dependencies affect transformation rule selection.
#
# If issue10.e is wanted and both issue10.d and issue10.f are available,
# make should choose the .d.e rule, because .d is before .f in .SUFFIXES.
# The bug was that if issue10.d had an explicit dependency on issue10.f,
# it would choose .f.e instead.
