multiple .PHONY or single .PHONY

[Martin d'Anjou]

Hello,

Is it okay to declare .PHONY multiple times, scattered throughout the 
makefile like this:

.PHONY: all
.PHONY: clean
.PHONY: other

Or must all .PHONY targets be consolidated into a single .PHONY 
declaration like this:

.PHONY:all clean other

Thanks,
Martin
