Yes it is, I meant noinst_, but my fingers typed nodist_ :-/

That's what I meant.

This is implied.  If no sources are given, $PROGRAMNAME.c is used by 
default.

It depends on the compiler you use.  If you have configured with a 
crosscompiler, it will do that yes.  Maybe you can override it?  You 
would have to copy the compile and link rules from the generated 
Makefile into your Makefile.am, and then change the compiler to 
$(CC_BUILD) or something...

I didn't see your other message until after I answered this one.  You 
are right that it would be nicer if Automake had built in support for 
such things.

Cheers,
        Gary.
