Not a bug, this is intentional.

std::unexpected_handler does not exist in C++17 and later, so using
terminate_handler means the code compiles for any version of C++. The two types
are identical, so it doesn't matter.

ah my bad then i just thought it looked suspicious especially since i been
having problems building gnat. For some reason it tries to link to the static
libgcc library and aborts due to an exception. So i had to change the
GCC_LINKER_FLAGS to force -shared-libgcc. so when i spotted this i assumed a
typo might have occured breaking the exception handlers.
