    on Intel:

    GCC-2.x did create 30% slower code than SunPro C for the code I did test
    GCC-3.3 still creates 14% slower code

    The code I currently use for testing is a Reed Solomon coder for CD-Data->
    CD-Audio sectors.

    If you like to repeat the test, get a recent cdrtools source
    ftp://ftp.berlios.de/pub/cdrecord/alpha/
    compile it and then chdir to libedc_ecc, call make -f speed.mk
    then run OBJ/<arch-specific>/edcspeed
