It is not.  These are the sizes of our 5 binaries, w/ and w/o -frepo:

		w/o -frepo  w/ -frepo

binary #1:	1789312      846304
binary #2:	3281592     2006712
binary #3:	 774176      512448
binary #4:	1067408      623248
binary #5:	1649944     1171096

I think the size reduction is huge, and it is worth using -frepo to
get it, it is just that is soooo painful...

Moreover, we were unable to resolve all the undefined symbols (they
are mangled and c++-filt can't unmangle them) in one of our most
template intensive libraries, and thus I believe the size can be
decreased even further.
