I understand your concerns, but it seems unfair not to test anything because 
some libraries have problems on como. Is it possible to setup a como test 
suite that only tests libraries that aren't affected by (1) or (2)? This 
would presumably address (4) as well.

As for (5), I'm very interested in seeing the test results of running a 
strict EDG-based compiler. It is true that few of us use como as our primary 
compiler, but it helps people write correct code, instead of code that just 
happens to compile on our test matrix. The latest Metrowerks and g++ seem 
promising, but I'm not sure whether they can displace EDG as a test platform 
yet when strict conformance is desired.
