STATUS: Under investigation. Experts on MMX assembler code are
invited to help with the debugging. Note that pngvcrd.c works fine.
Update: fixed in libpng-1.0.8beta1. It compiles under gcc-2.7.2.3
and seems to work; under gcc-2.7.2.1 it compiles but crashes in
execution. It is recommended that people use 2.95.2 or later.
The png_read_filter() function has still not been fully converted and
will not compile under gcc-2.95.2; it is currently ifdef'ed out.
