-; * the gcc -S output of zlib-1.2.0/inffast.c. Zlib-1.2.0 is in beta release at\r
-; * the moment. I have successfully compiled and tested this code with gcc2.96,\r
-; * gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S\r
-; * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX\r
-; * enabled. I will attempt to merge the MMX code into this version. Newer\r
