Interesting.  I consider myself pretty experienced
with bash but I didn't know that setting variable
on the same command line before the command exports
them to the command.
Thanks for the tip.

I did that and it didn't take.
I added file3.c to foo_SOURCES but it didn't compile
file3.c when I ran make.
But when I added #include "header3.h" in file2.c then
it compiled file3.c.

Does the order that the
files are listed make a difference?
