HI All:
When I build my big project , the make takes about 2.45 minutes to include all
makefile and then start to build.One question:Can Make store the makefile datas
for the next build, especially for the incremental building.
I thinks this is a good feature for make.
thanks :)_

Yes that is what I hope will be done.

But they're not the same. The second one will override a setting of
'a' in the Makefile, the first one won't.

They're not quite equivalent, although an example like the one you give
may be a good one for the documentat
