I take it back: my algorithm is failing to eliminate some identical
states, and all those solutions are equivalent; let me fix that and it
should run faster.

However, let me also say that the optimal path which produces EST_EXE
from those sources in the fewest transformations looks nothing like
the one you wanted anyway, which is another argument for specifying
intermediate main targets. The optimal path is:

/ \
ecpp --< >--
\ / \
-->cpp------->obj-- \
cpp------------------->obj-- /
\ /
--> cpp---->obj--
nm_asm --<
--> static_data

which is described by all three results I posted earlier.
