much of the sourceware tree has converted.  seems the only major dirs not 
using it are newlib/libgloss/gdb/sim.
$ ls `find -name Makefile.in | sed 's:[.]in:.am:g'`

not saying this means "gdb/sim must convert", just providing more context to 
show that it's inevitable ! :)

i'm not sure what you mean by machine generated files.  could you provide 
specific examples ?

just having dependency info in the current dir would be a vast improvement.  
i'll poke the gdb system to see how it's doing it.
