The gcc 4.1 man page says:
-fobjc-exceptions
Enable syntactic support for structured exception
handling in Objective-C,
similar to what is offered by C++ and Java. Currently,
this option is only
available in conjunction with the NeXT runtime on Mac OS
X 10.3 and later.
However, gnustep-base seems to have some support for this; if you
build gnustep-make with --enable-native-objc-exceptions, then small
test programs I've written "seem to work" (with the gnu runtime on
linux x86).
Does anyone know what the real story is here? It would be really nice
to dispense with the crufty old setjmp/longjmp stuff -- in
particular, with the need to declare certain variables volatile.
(I've determined by experimentation that bugs due to undeclared
volatility are fixed by switching to native exceptions.)
