  2 warnings generated.

The warnings refer to the default case of a switch statement over an
enum variable, clang fails to understand that the default case can still
be reached because any integer value can be assigned to the enum
variables via the atoi() function. Work around the warning.

The behavior is also documented here:
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-September/024174.html

In general assigning arbitrary values to enum variables will just be
weird; using enums in read mode is always safe tho.
