The list below contains a proposed set of compiler requirements for future releases of the Apache C++ Standard Library. These requirements are features that were not ubiquitous across compilers in the past as they are in modern compilers. As such, the corresponding configuration checks for such features can be ignored and feature support can be safely assumed when writing new code.
bool type and true, false keywords (_RWSTD_NO_BOOL)
_RWSTD_NO_NAMESPACE)
