It's because they're the difference from the current version - so the older the version the more differences. So PC_COMPAT_2_5 has no differences, PC_COMPAT_2_4 is 2_5's differences (none) plus a handful of CPU differences. The PC_COMPAT_2_3 is PC_COMPAT_2_4's differences plus a bunch of differences that went in between 2.3 and 2.4. Dave -- Dr. David Alan Gilbert / [email protected] / Manchester, UK
