Use makefile.nommx

The 64-bit compilers won't assemble the MMX assembly code
properly.

Like this:

-Wall -O3
-funroll-loops -fomit-frame-pointer   -o pnggccrd.o
pnggccrd.c

I've heard that other platforms will claim to have
assembled
pnggccrd.c OK but then you get a runtime crash.

I'm testing on a RedHat Enterprise 64-bit machine with dual
cpu:

uname -a
Linux [host.domain] 2.6.9-42.0.8.ELsmp #1 SMP Tue Jan 23

2007 x86_64 x86_64 x86_64 GNU/Linux
