My mailserver has just crashed and looks like
being down for the weekend at least, so I've
temporarily subscribed from this address... :<

(Please complain at me privately if it does
something horrible like send HTML mail: I think
I've turned all that stuff off, but ...)

I understand your concern.  I'm happy with your
proposal as long as 1.6 comes out a matter of months
after 1.5, rather than years. ;-)

Making a branch for 1.5 should concentrate the mind
nicely, too.

I'll leave it to you to make the branch...

It should do.  Making this work is a good chunk of
the code...
As far as I know, the behaviour should be identical
after the patch to that beforehand.

Substitutions are implemented (as before) by
processing the value at automake runtime, rather
than putting appropriate substitutions in the
makefile.  This means that configure substitutions
and "make MYSRC=foo.c" overrides won't work correctly
(the former is at least warned about).  If we're
prepared to require make to support substitution
references, I think we could fix this eventually,
though.  If we're not prepared to require substitution
references, we still need to do some fixing so that
the _SOURCES variables (and any others) have the
substituions worked out by automake: currently they're
just left in the
