Comment:

 If you pass GHC the -v flag, then you can see what commands it's running,
 so you will be able to see the difference between using the `-pgm*` flags
 and changing the compiler in the `settings` file.

 I suspect that what you're running into is that using a `-pgmX` flag
 empties the flag list for `X`, so you will need to use `-optX` flags to
 add any necessary flags again. This is deliberate, as the current flag
 list is designed for a different `X`, so you may not want to use these
 flags with the new `X` (the new `X` may not even support them).

 If you still think there's a bug, please reopen and give more details
 about what's happening, and what you think should happen.
