I don't have any doubts about whether GHC can make sense of
conflicting options or not, be it the one way or the other.  What's
causing the trouble is that part of the intent specified on the
command line is not carried-out by the compiler, and the only way to
diagnose (or even be aware of) such occurrences seems to be searching
through the manual, perhaps without even knowing what one is looking
for.

I for one would find it quite helpful to see a warning line for each
overriden option, if without so much of an explanation -- a "red
light" to let me know something might be wrong.
