Why are you using <malloc.h>?  Use <stdlib.h> for malloc().  It's ANSI
compliant.  This shouldn't be causing you a problem, though.

The problem is the *array++=1; statement.  array is an array of longs.
1 is an int. (short).  Try one of these:

	*array++ = 1L;

or:

	(SHORT)(*array++) = 1;

The first example is probably better.  

If you don't want to change anythings, try using a lower warning level
(/w3 may be too high for this kind of operation).  Or turn off
ANSI-compliant type-checking.
