That would require some actual modules written in C++ that illustrate the disasters of allowing exceptions to propagate into C code, which I presume would be some work. I briefly looked into this and though I am by no means a C++ expert it appears that we went over the edge of the standard on that one, so in commit 552694a2653b4f9cde515139d01793a5a0e964b7 I reverted both changes and moved the problematic typedef out of the public .h file (where it would just be a bug magnet anyway, apparently) and into our private .c file.
