[Bug libobjc/27466] New: RFE: Support for libobjc equivalent of std::set_unexpected

[landonf at opendarwin dot org]

libobjc's exception implementation doesn't support a user-supplied default
uncaught exception handler, and this would be a very handy feature to have.

With the equivalent of std:set_unexpected, one could implement the
NSSetUncaughtExceptionHandler() Foundation API.

It will most likely be called objc_set_unexpected like all other libobjc
functions and then GNUStep will implement NSSetUncaughtExceptionHandler.

An implementation of objc_set_unexpected function

We really need this function to use native objective-c in GNUstep.
The tiny attached patch does what the gnustep-base library needs ... providing
a function to set a hanlder to be called if an exception is not caught.  Please
could you apply it or something similar.

Any news on when this can be done?  The path is tiny/trivial, so even though it
might be judged low priority I'd have hoped it could be fitted in quickly.

I just checked up on this again ... 
The problem was initially reported two and a half years ago.
I supplied a (very very simple) patch to fix it a month ago.
Could someone please apply the patch so it gets into the next release?
