libunwind also provides this header.  libcxxrt provides its own version with some compatibility macros to allow Itanium and ARM EH personality functions to easily share code.  Between libunwind and compiler-rt, you have most of the code that you need to replace libgcc_s.  This is on my todo list for FreeBSD.
