# No need to define .SUFFIXES because we don't use any suffix rules
# Instead we use gmake's pattern rules exlusively

.SUFFIXES:

# However, if $(way) is set then we have to define $(way_) and $(_way)
# from it in the obvious fashion.
# This must be done here (or earlier), but not in target.mk with the other
# way management, because the pattern rules in this file take a snapshot of
# the value of $(way_) and $(_way), and it's no good setting them later!

# The .hi file depends on the .o file,
# so if the .hi file is dated earlier than the .o file (commonly the case,
# when interfaces are stable) this rule just makes sure that the .o file,
# is up to date.  Then it does nothing to generate the .hi file from the 
# .o file, because the act of making sure the .o file is up to date also
# updates the .hi file (if necessary).
