The problem with aliasing is that the user would be allowed to write something like this:
-fcx-limited-range -fcomplex-arithmetic=improved
This will generate a warning like this:
warning: overriding '-fcomplex-arithmetic=basic' option with '-fcomplex-arithmetic=improved' [-Woverriding-option]

This warning is a bit mis-leading and doesn't reflect the option used in the command line. Not sure this can be corrected.
