+** ('osize' is the old size, 'nsize' is the new size)
+**
+** * frealloc(ud, NULL, x, s) creates a new block of size 's' (no
+** matter 'x').
+**
+** * frealloc(ud, p, x, 0) frees the block 'p'
+** (in this specific case, frealloc must return NULL);
+** particularly, frealloc(ud, NULL, 0, 0) does nothing
+** (which is equivalent to free(NULL) in ISO C)
+**
+** frealloc returns NULL if it cannot create or reallocate the area
+** (any reallocation to an equal or smaller size cannot fail!)
