-frepo works great on egcs-1.1

[Mumit Khan <khan at xraylith dot wisc dot edu>]

With the improved template and NS support in 1.1, -frepo works like a
charm on a few non-ELF/non-PE platforms I've tried. Works *much* better
than explicit instantiation, and the resulting sizes are quite a bit
smaller than explicit.

Interestingly enough, I can't get -frepo to work on i386-pc-linux-gnu!
Never caught it before since I never bothered to try it until now. I'll
check more into it and hopefully submit a meaningful bug report. 

Mike Stump at one point had asked for testimonial on how -frepo works vs
explicit instantiation. Now, at least for my own code that makes heavy
use of STL and expression templates, it works faster and better than
explicit. Also, coming up with the needed explicit instantiations has
become too cumbersome even with scripts that generate these from linker
errors.

Thanks for all the great work.
