# npbparams.h is included by header.h
# The following rule should do the trick but many make programs (not gmake)
# will do the wrong thing and rebuild the world every time (because the
# mod time on header.h is not changed. One solution would be to 
# touch header.h but this might cause confusion if someone has
# accidentally deleted it. Instead, make the dependency on npbparams.h
# explicit in all the lines below (even though dependence is indirect). 

# header.h: npbparams.h
