-;/* inffas32.asm is a hand tuned assembler version of inffast.c -- fast decoding

-; * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
-; * the gcc -S output of zlib-1.2.0/inffast.c.  Zlib-1.2.0 is in beta release at
-; * the moment.  I have successfully compiled and tested this code with gcc2.96,
-; * gcc3.2, icc5.0, msvc6.0.  It is very close to the speed of inffast.S
-; * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
-; * enabled.  I will attempt to merge the MMX code into this version.  Newer
-; * versions of this and inffast.S can be found at
-; * http://www.eetbeetee.com/zlib/ and http://www.charm.net/~christop/zlib/
