Richard asked also for numbers from Linux kernel build, so I've built linux-2.6 git faf80d62e44dc627efb741f48db50c1858d1667c make allyesconfig; make on x86_64. With make allyesconfig; make -j64 and trunk@148582 (--enable-checking=release) it took 9m12s, with vta@149180 it took 9m15s. With make -j1 the same took 1h43m2s on trunk@148582 and 1h48m11s on vta@149180. .debug_info+.debug_loc+.debug_abbrev section sum grew by 1.9MB out of 422MB, the most of the debug info comes from huge headers and there locations weren't really changing.
