# makefile for libpng.a and libpng12.so on Linux ELF with gcc using MMX

# CAUTION: Do not use this makefile with gcc versions 2.7.2.2 and earlier.
# WARNING: The assembler code in pnggccrd.c may not be thread safe.
# NOTE: When testing MMX performance on a multitasking system, make sure
# there are no floating-point programs (e.g., SETI@Home) running in
# the background! Context switches between MMX and FPU are expensive.
