Log Message:
tests/lint: add test for incompatible enums in switch

Neither lint nor GCC 10 nor Clang 8 have a warning for an enum type
mismatch in a switch statement.

GCC 10 issues a warning but completely misses the point of the
mismatched enum types.  It only warns because in this test, EVENING has
the numeric value 3, which is out of bounds for enum color, where the
valid range is from 0 to 2.  It says:

> msg_130.c:45:2: warning:
>     case value ‘3’ not in enumerated type ‘enum color’ [-Wswitch]

Clang 8 behaves almost the same, it just doesn't mention the value of
the constant, saying merely 'case value not in enumerated type'.
