Um, calloc is the same as malloc + zero. Those two seem identical to me.

 2. describe only does an mbvalidate for WIN32, but print does it in all cases.

There's this comment in describe.c:

/*
 * mbvalidate() is used in function describeOneTableDetails() to make sure
 * all characters of the cells will be printed to the DOS console in a
 * correct way
 */

I don't know what that's about. Perhaps there's something in the archives...
