Alistair, this will not work because the target and depency do not have 
the same root name (see for yourself in pkg/mnc/Makefile):
MNC_CW_READWRITE_RS.F: mnc_cw_readwrite.template
	cat $< | sed -e 's/RX/RS/g' | sed -e 's/__V/_RS/g' > $@
MNC_CW_READWRITE_RL.F: mnc_cw_readwrite.template
	cat $< | sed -e 's/RX/RL/g' | sed -e 's/__V/_RL/g' > $@
MNC_CW_READWRITE_I.F: mnc_cw_readwrite.template
	cat $< | sed -e 's/RX/I/g' | sed -e 's/__V/INTEGER/g' > $@

These are actually the only three instances of a .template.F rule. It 
may make sense to replace $< with mnc_cw_readwrite.template in these 
three cases, as long as Ed didn't plan to extend this Makefile 
infinitely. Ed, what's your opinion?
