/* CRT_LEGACY_WORKAROUND should only be defined when building

|
|
* The C library already defines a function named 'atexit()'
|
|
* for backwards compatibility with older NDK-generated binaries.
|
|
*
|
|
* For newer ones, 'atexit' is actually embedded in the C
|
|
* runtime objects that are linked into the final ELF
|
|
* binary (shared library or executable), and will call
|
|
* __cxa_atexit() in order to un-register any atexit()
|
|
* handler when a library is unloaded.
|
|
*
|
|
* This function must be global *and* hidden. Only the
|
|
* code inside the same ELF binary should be able to access it.
