To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG. The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.

|

// (which is determined by architecture-specific logic). But the C++
|
|
// compiler may believe that size_t is of a different type resulting in
|
|
// compilation errors in the operator. Using the underlying integer type
|
|
// instead of size_t seems to resolve the compilation issues. Need to
|
|
// REVISIT this.
