Weird -- the exact opposite happens for me (if I touch btl.h, it
automatically rebuilds oodles of stuff, to include bml_r2.c).
I have dim recollections of Automake disabling dependency tracking by
default on Solaris+Solaris compilers (I don't remember the exact issue
-- perhaps it was before AM supported the dependency format of the
Solaris compilers...?). Have you tried configuring with --enable-
dependency-tracking?

I was playing with OMPI and I noticed that if I modified btl.h,
bml_r2.c did not automatically get rebuilt, even though it includes
btl.h. This caused me all sorts of unnecessary debugging troubles.
In the end, just touching bml_r2.c was enough... it caused bml_r2.c
to be recompiled and to see the changes in btl.h.
So, question:
Given that bml_rc.2 includes btl.h, wouldn't the proper make
dependencies cause bml_rc.c to be recompiled whenever btl.h is
touched?
Again, it appears that this is not happening and that strikes me as
a problem -- for someone out there to fix. :^)
