 A word on short-integers and SAS/C (a bug of [mc]alloc?)
 Using short integers (i.e. compiling with option SHORT-INTEGERS) is
 *not* recommended. To get maximum compression ratio the window size stored
 in WSIZE should be 32k (0x8000). However, since the size of the window[]
 array is 2*WSIZE, 65536 bytes must be allocated. The calloc function can
 only allocate UINT_MAX (defined in limits.h) bytes which is one byte short
 (65535) of the maximum window size if you are compiling with short-ints.
 You'll get an error message "Out of memory (window allocation)" whenever
 you try to deflate. Note that the compiler won't produce any warning.
 The maximum window size with short-integers is therefore 32768 bytes.
 The following is only implemented to allow the use of short-integers but
 it is once again not recommended because of a loss in compression ratio.
