Exception handling in C?

[williams at cs.umass.edu]

I would like to hear of peoples experiences using exception handling
in C - both pro and con.  Don't most people find that returning error
status codes becomes very hard to handle (no pun intended) in larger
software systems?

There was a paper about 7 or so years ago in an ACM publication discussing
this and providing macros to implement it in C.  Can anyone provide
the reference (or even better a copy of the article!) or other, more
recent ones?  Have any of the many C books on the market discussed
exception handling in C?
