Hi, I'm using -Wextra (-W) to compile my code, one
feature of which is throwing a warning when an
unsigned type is checked for >= 0 since it's always
true. In general I find this to be very helpful, but
it throws this error even for templated types. A code
example is included below. Does anyone know how best
to supress this warning without resorting to removing
the condition or turning off -Wextra? Thank you in
advance.
template <typename T>
struct foo {
foo(T bar) { if (bar >= 0) bar = 1; }
};
If foo<signed type> is instantiated elsewhere then
this check could still be useful.
I apologize in advance if this question is better
suited to gcc-help. I tried there, and not having
gotten an answer I fear it may be a defect in -Wextra
so I took it up here.
