ax_cxx_dtor_after_atexit

Synopsis

AX_CXX_DTOR_AFTER_ATEXIT

Description

If the C++ compiler calls global destructors after atexit functions, define HAVE_DTOR_AFTER_ATEXIT.

Conformant behavior is to have global destructors after atexit

Per Paragraph 3.6.3/1 of the C++11 Standard:

Destructors (12.4) for initialized objects [..] with static storage duration are called as a result of returning from main and as a result of calling std::exit (18.5).

And per Paragraph 3.6.3/3:

If the completion of the initialization of an object with static storage duration is sequenced before a call to std::atexit [..], the call to the function passed to std::atexit is sequenced before the call to the destructor for the object.

WARNING: If cross-compiling, the test cannot be performed, the default action is to define HAVE_DTOR_AFTER_ATEXIT.
