#ifdef _DEBUG
// From
// and
// there appear to be two types of STL container checking. The
// former is enabled by -D_DEBUG (which is implied by -MDd or -MTd), and
// looks to be full generation/mutation checked iterators as done by
// _GLIBCXX_DEBUG. The latter appears to just be bounds checking, and
// is enabled by the following macros. It appears that the _DEBUG
// iterators subsume _SECURE_SCL, and the following settings are
// default anyway, so we'll just leave this commented out.
//# define _SECURE_SCL 1
//# define _SECURE_SCL_THROWS 0
// Note: _SECURE_SCL iterators are on by default in opt builds. We
// could leave them on, but since gcc doesn't, we might as well
// preserve that behavior for perf reasons. nsTArray is in the same
// camp as gcc. Can revisit later.
// FIXME/bug 551254: because we're not wrapping all the STL headers we
// use, undefining this here can cause some headers to be built with
// iterator checking and others not. Turning this off until we have a
// better plan.
//# undef _SECURE_SCL
// C4275: When _HAS_EXCEPTIONS is set to 0, system STL header
// will generate the warning which we can't modify.
// C4530: We know that code won't be able to catch exceptions,
// but that's OK because we're not throwing them.
