Are you sure? I tried very simple program using shared_ptr and it's OK 
in non-strict mode, but does not compile in strict mode. The only 
difference is --a switch. In strict mode it chokes on interlocked.hpp 
header, but apparently the very same header is accepted in non-strict 
mode. Which would mean that without --a switch Comeau knows how to deal 
with __stdcall. Actually I'm pretty sure that wihout --a como can 
compile program than includes Windows headers, I tried it more than 
once. Or maybe I misunderstood something and some different experiment 
would be relevant (but not the one shown below)?
