Log Message:
lint: warn about pointer casts between different kinds of types

Pointer casts from an integer type to a floating-point type and vice
versa get a 'maybe troublesome' warning now.  The previous assumption
that all types of the same bit-size are convertible may have been valid
from a technical point of view, but still such code should get more
attention.

The rules for struct and union types could be made more fine-grained
later, if the need arises.  To suppress this warning, it's always
possible to cast to an intermediate 'void *'.
