-/* Offsets for fields in the deflate_state structure. These numbers
- * are calculated from the definition of deflate_state, with the
- * assumption that the compiler will dword-align the fields. (Thus,
- * changing the definition of deflate_state could easily cause this
- * program to crash horribly, without so much as a warning at
- * compile time. Sigh.)
+/* All the +zlib1222add offsets are due to the addition of fields
+ *  in zlib in the deflate_state structure since the asm code was first written
+ * (if you compile with zlib 1.0.4 or older, use "zlib1222add equ (-4)").
+ * (if you compile with zlib between 1.0.5 and 1.2.2.1, use "zlib1222add equ 0").
+ * if you compile with zlib 1.2.2.2 or later , use "zlib1222add equ 8").
