    This function increments @a value in an atomic manner.

    Whenever possible wxWidgets provides an efficient, CPU-specific,
    implementation of this function. If such implementation is available, the
    symbol wxHAS_ATOMIC_OPS is defined. Otherwise this function still exists
    but is implemented in a generic way using a critical section which can be
    prohibitively expensive for use in performance-sensitive code.
