Hi,
I found an issue that the __cxa_thread_atexit_impl() function never called by
__cxa_thread_atexit() even with newest glibc which have __cxa_thread_atexit_impl
implemented.
It turns out that the code tried to use macro HAVE___CXA_THREAD_ATEXIT_IMPL, but
not _GLIBCXX_HAVE___CXA_THREAD_ATEXIT_IMPL which is defined in bits/c++config.h
(generated from autoconf scripts).
This patch adds the missing macro prefix.
Thanks,
Zifei
