OK, in that case there is no need to use per-target flags.

Let me show an example:

bin_PROGRAMS = first second third
first_SOURCES = first.c
second_SOURCES = second.c
third_SOURCES = third.c

second_CFLAGS = ...

In this example, `AM_CFLAGS' is used for all programs, with one
exception: when compiling program `third', `third_CFLAGS' is used

This `third_CFLAGS' is called per-target variable, and overrides the
corresponding general one AM_CFLAGS.

The mechanism is the same in your case, when you are using *_CPPFLAGS
instead of *_CFLAGS.

Since you have only one program, you can set `AM_CPPFLAGS' as needed
for the program `editorD', and there is no need to use the override

Then, because of some internal mechanisms of Automake, the suffix
rule `.asm.o' will be used, and you can redefine it if you like.

Start with the following code, adding back the things you removed
to simplify the example.
