I have found, that this program does not compile, if better
optimizations than -O2 are used:

http://divx.euro.ru

It is C++-software, that can be used for decoding and encoding of
ASF-files and AVI-files using Divx ;-) -codec 

I tried these options:

CC=/usr/local/pggc/bin/gcc \
CXX=/usr/local/pggc/bin/g++ \
CPP=/usr/local/pggc/bin/gcc \
CFLAGS='-O6 -Os -march=pentium -mcpu=pentium -malign-double -mstack-align-double -funroll-all-loops' \
CXXFLAGS='-O6 -Os -march=pentium -mcpu=pentium -malign-double -mstack-align-double -funroll-all-loops' \
CPPFLAGS='-O6 -Os -march=pentium -mcpu=pentium -malign-double -mstack-align-double -funroll-all-loops'

If I remember correctly, also this software had some problems, when
compiled with Pentium-GCC with options:

http://www.mpg123.de/

I used this stabbed version of Ilpo "Ashitaka" Ruotsalainen:

http://www.ee.oulu.fi/%7Elonewolf/files/

There is a target called "linux-lonewolf" in that Makefile, so use it.
But I created this:

linux-juhtolv:
        $(MAKE) CC=/usr/local/pggc/bin/gcc CPP=/usr/local/pggc/bin/gcc \
                LDFLAGS= \
                OBJECTS='decode_i386.o dct64_i386.o decode_i586.o \
                        audio_oss.o term.o' \
                CFLAGS='-DI386_ASSEM -DREAL_IS_FLOAT -DPENTIUM_OPT -DLINUX \
                        -DREAD_MMAP -DOSS -DNO_WAV -DTERM_CONTROL \
                        -Wall -O6 -march=pentium -mcpu=pentium \
                        -fomit-frame-pointer -funroll-all-loops \
                        -malign-loops=2 -malign-jumps=2 -malign-functions=2 \
                        -finline-functions -ffast-math \
                        -malign-double -mstack-align-double'\
                mpg123-make
