// With MSVC, the default type of an enum is always signed, even if one of the
// enumerator values is too large to fit into a signed integer but would
// otherwise fit into an unsigned integer.  As a result of this, all of LLDB's
// flag-style enumerations that specify something like eValueFoo = 1u << 31
// result in negative values.  This usually just results in a benign warning,
// but in a few places we actually do comparisons on the enum values, which
// would cause a real bug.  Furthermore, there's no way to silence only this
// warning, as it's part of -Wmicrosoft which also catches a whole slew of
// other useful issues.
//
// To make matters worse, early versions of SWIG don't recognize the syntax of
// specifying the underlying type of an enum (and Python doesn't care anyway)
// so we need a way to specify the underlying type when the enum is being used
// from C++ code, but just use a regular enum when swig is pre-processing.
