is shouldn't SCons delete the target if the builder fails?  I thought SCons
always deletes the target(s) before running a builder, so I'm guessing in
his case the builder wrote a partial output file and then failed.  I think
in this case it probably does make sense for SCons to delete the failed
output file.  Opinions?
