Just to follow up: native FreeDOS (on this same 3.2 Ghz machine), XMS only, LBAcache loaded, everything on RAM disk, all binaries uncompressed, it only takes about three minutes (3:14) to rebuild 7ZA.EXE. With LFNs enabled (thus avoiding some ugly patches I made), while resulting in the same CRC32, it's much slower at about nine minutes (9:06). EDIT: I can shorten it from 3:14 to 2:46 if I load "hdpmi32 -r" (HX 2.18) first. Saves 15% of time (roughly 30 secs).

So I wouldn't call three or even eight or nine minutes horrible. I know this isn't something you'd compile every day from scratch either. Still, it is curious how much it varies. Also, good to know that newer G++ versions aren't too much slower to rebuild stuff.
