I can't speak to users, but an issue with C99 is that part of the 
functionality comes from the compiler and part from the system 
libraries.  The compiler is often easily updated but the system 
libraries may be set in stone and not support C99 features.  The %zu 
syntax would be coming from system libraries.

Milter-greylist likely does not care about Microsoft compilers but %zu 
syntax has been a problem there until almost recent compilers.  With 
Microsoft, newer compilers produce output which do not run on older 
systems that many people are still using.

If C99 is a requirement, then the milter-greylist code should be 
substantially updated to take advantage of beneficial features.
