// Standard includes

// This header includes almost everything we use out of the standard library.
// This is a pre-compiled header. Project build time is significantly reduced
// by doing things this way and C++ std headers have very little namespace
// pollution and risk of conflicts.
//

// It is advised that all standard library symbols are declared with default
// visibility. This pragma overrides any -fvisibility option on any unit.
