+ *  Declare compile-time assertions, results in compile-time error if condition is false
+ *
+ *  The assertion acts as a declaration that can be placed at file scope, in a
+ *  code block (except after a label), or as a member of a C++ class/struct/union.
+ *
+ *  @note
+ *  Use of MBED_STATIC_ASSERT as a member of a struct/union is limited:
+ *  - In C++, MBED_STATIC_ASSERT is valid in class/struct/union scope.
+ *  - In C, MBED_STATIC_ASSERT is not valid in struct/union scope, and
+ *    MBED_STRUCT_STATIC_ASSERT is provided as an alternative that is valid
+ *    in C and C++ class/struct/union scope.
+ *
+ *  @code
+ *  MBED_STATIC_ASSERT(MBED_LIBRARY_VERSION >= 120,
+ *          "The mbed library must be at least version 120");

+ *  int main() {
+ *      MBED_STATIC_ASSERT(sizeof(int) >= sizeof(char),
+ *              "An int must be larger than a char");
