Re: how to make _DEPENDENCIES appear earlier in prerequisite

[n.g.]

it seems that if something appeared in the same place in a Makefile, they are 
not ordered. ex. if they are both dependencies of a target.

currently, the problem is solved by using BUILT_SOURCES and/or manual rules for 
sources. as you mentioned.

if automake will accept userdefined rule to be act as builtin primaries, 
it will be a wonderful thing.

or if automake populate the macro it used to canonicalize macro names for user 
use is not bad too.
