We could go further and remove the ABI difference in regex_compiler
when using _GLIBCXX_DEBUG, as in the attached patch.
The trick is that for the char specialization we have padding bytes
between _M_is_non_matching (a bool) and _M_cache (a std::bitset), so
we can reuse one of those padding bytes

Darwin bits Ok.
The standard says that unique_ptr::operator->() and
shared_ptr::operator->() have preconditions that the pointer is not
null, but that's not strictly necessary and prevents using that
function to get a raw pointer from a smart pointer in generic code.
This changes the _GLIBCXX_DEBUG_ASSERT to _GL

Hi,
For some Darwin compilers, "-arch " can be used (a) in place of, but to
indicate the same as, a multilib flag like "-m32" and (b) multiple times to
indicate that the User wants a FAT object with multiple arch slices.
It's helpful to support this, as far as possible, to minimise build sy
