That still leaves open the question: what is the risk of using ASMINF?  
How exhaustively has the assembler code been tested?  Has someone other 
than the author walked through the assembler source code to validate 
it?  I'm nervous since making it part of the zlib1.dll available from 
the zlib web site means that I'll have to support it.
