I've read the latest FAQ, and it implies that exception handling is 
available, unless they mean something like Linux, or solaris when they 
say exception handling is available for x86. It doesn't seem to be 
working for me though, so can someone tell me if exception handling 
simply isn't available yet for DOS, or if I've done something wrong?

The symptoms: I've compiled GCC 2.7.2 and libg++-2.7.1 (hopefully 
correctly - that remains to be seen). Simple hello, world programs seem 
to work in C and C++, but I admit to not trying any more complex 
programs. I've written a small program which basically throws an 
exceptions and outputs messages to trace the flow of code. I compile with 
the -fhandle-exceptions flag and attempt to link but get the following 
errors:

In function 'main' - undefined reference to 'terminate(void)'
In function '__throw" undefined reference to 'terminate(void)'

I've poked around in the likeliest (to me) spot - except.c - and found 
lots of comments. Is this particular implementation not complete yet, or 
did my build fail at some point?

Thanks in advance for any help.
