+@itemdef{wxHAS_ATOMIC_OPS, Defined if wxAtomicInc() and wxAtomicDec() functions
+ have an efficient (CPU-specific) implementation. Notice that the functions
+ themselves are always available but can be prohibitively slow to use when
+ implemented in a generic way, using a critical section.}
+@itemdef{wxHAS_CONFIG_TEMPLATE_RW, Defined if the currently used compiler
+ supports template Read() and Write() methods in wxConfig.}
