Comment (by kencu):

 FYI Iain told me he could not get the exceptions to work properly with the
 old system libgcc_s_1.dylib and had to replace the system version with the
 newer version from the gcc7+ build to get it working right.

 For a while we discussed an installer that might replace the older libgcc
 parts on PPC Darwin with newer libgcc parts, but in the end we knew that
 would likely never fly so abandoned the idea.
