Hmm.. that is easier said than done..:-( And I am precisely trying to avoid 
it..I would love to re-organize the sources but that has far higher impact 
since per module regression test need to be redone too..

Thing is, when the project built on HP-UX, it uses one archive library per 
module. On linux I have converted it to one shared library per module. 

Ideally the same set of libraries i.e. -lfoo1 -lfoo2 etc.,  should suffice for 
linking in both the scenarios.

But it is not..Looks like it is a hard way to go..

I am using jam from perforce which I found to be better than automake. I don't 
think I need autoconf because the platforms are *very* tightly controlled.

Just a personal experience.
