* If C++ and C++ static constructors are supported, then this function

* initialization of the static C++ class instances.
*
* This function should then be called in the application-specific
* user_start logic in order to perform the C++ initialization. NOTE
* that no component of the core NuttX RTOS logic is involved; this
* function definition only provides the 'contract' between application
* specific C++ code and platform-specific toolchain support.
