Gcc 4.9 binaries on OpenBSD/amd64 are resonable: -r-xr-xr-x 1 root bin 11.6M Sep 9 03:02 cc1 -r-xr-xr-x 1 root bin 15.4M Sep 9 03:02 gnat1 -r-xr-xr-x 1 root bin 749K Sep 9 03:02 ecpp There is indeed a problem with huge binaries on OpenBSD/arm, which I've not yet figured out, but i386/amd64/sparc64 are fine.
