You need to test for this support in configure.ac. It's as simple as
adding a call to AX_GCC_FUNC_ATTRIBUTE in the existing alphabetized

Should the code fallbacks on atexit(3) if the attribute is not
supported?
At least on Windows, with MSVC, atexit should be the right thing to do,
since we statically link MSVC RunTime,

For the record, another alternative (way more portable), is you have a
simple .cpp file with a static destructior:
class AtExit
{
public:
~AtExit() {
// do what must be done
}
};
AtExit atExit();
After all, it seems wrong to use non-standard C to replicate what
standard C++ can do.
