SubjectRe: 2.4.9 does not compile [PATCH]

2. This macro doesn't produce a warning like the typeof version does.
The typeof version warns you about signed/unsigned compares, while an
assignment gives no warning.

That is a legitimate operation, there is no reason to prevent people
from comparing signed and unsigned values. These type argument
min/max values allow people to specify what the comparison type
degenerates into.
