I've always used it for 'make world' and kernel compiles in my 486's, but now that I'm using a PPro I suppose it's useless, no? Is gcc ever going to support -m686, etc? I think there is a pentium optimized version (pgcc?) -- has anyone ever tried doing a make world or kernel compile with it to see if it' actually better?
