Re: Exceptions

Thanks to Benjamin, I (we) have solved the issue that I was having below. 
One must be very careful to make sure that when compiling you are using
the correct compiler.  I apparently had a version of egcs-2.90.66 sitting
in my /usr/bin directory.  However, in doing a which I believed I was
using gcc in my /usr/local/bin.  So when I did a command line compile
everthing worked like a charm, but when I used my Makefile it defaulted to
/usr/bin thus using the wrong compiler and causing a number of problems.

So the moral of the story is?  Got milk?

Thanks Benjamin.
