There's not anything specific to do that out of the box.

For things you suspect might be a problem you can capture the return 
value from the builder, which will be a list of SCons Nodes, which you 
can then examine. But your problem seems to be with a source...

ret = Program(target="foo", source=["foo.c])
for node in ret:
     print(node.name)

There is some issue where a target has the same name as a directory, 
maybe that's true for sources as well?  See:
