Thank you for the tips, Doug, I have used the code in my latest "sodium" PR.

You could do this:
 
: SODIUM_SIZE_MAX ( -- x ) cell-bits on-bits ;
 
where cell-bits gives 32/64 and on-bits turns them to ones.

Hello!

  I'm creating the sodium library FFI for Factor, and I found the following definition in the Sodium C headers:

#define SODIUM_MIN(A, B) ((A) < (B) ? (A) : (B))
#define SODIUM_SIZE_MAX SODIUM_MIN(UINT64_MAX, SIZE_MAX)

  I think SODIUM_SIZE_MAX is used as platform-dependent macro constant, which represents a maximum value for array sizes and similar memory limits.
  It'll have the max value of the size_t type, which is either 16-bit, 32-bit or 64-bit depending on the compilation target platform.

  How should I define the SODIUM_SIZE_MAX constant in Factor?
