I thought that Microsoft's compiler didn't have <stdint.h>. I've also heard that <inttypes.h> is more common. > The int_fast16_t and int_fast32_t types (and the unsigned versions) > are mandatory in <stdint.h>, so you can take it for granted that > /all/ compilers support them.

But int_fast16_t is useless to test whether code can be affected by 16-bit truncation on platforms for which int_fast16_t is really a 16-bit type. For tests, int16_t is necessary. Now the user may want to know what targets provide this type. -- Vincent Lefèvre <vincent@xxxxxxxxxx> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
