gcc cross mips output sizes too big

[David Wuertele <dave-gnus@bfnet.com>]

I've been using crosstool-generated gcc-3.3.3 to build my mipsel
targets, and I find that the file sizes are humungous.  After
stripping the objects, I get file sizes that are up to TWICE as large
as similarly generated gcc-2.96 code.  Do these sizes not look out of
line?

   bytes          gcc-3.3.3 generated files
  -------       --------------------------------
  1884160	/lib/libc-2.3.2.so
  1257472	/lib/libstdc++.so.5.0.5
  1048576	/usr/local/lib/libfreetype.so.1314.0.0.10
  1036288	/bin/busybox
  1011712	/bin/bash

   bytes          gcc-2.96 generated files
  -------       --------------------------------
  1531904	/lib/libc-2.2.4.so
  532480	/lib/libstdc++-3-libc6.2-2-2.10.0.so

Compiling with -Os helps, but doesn't get close to the file sizes I
saw with my older cross-compiler.  It seems strange to me that moving
to a newer compiler will reduce the number of programs I can ship in
my little NAND flash.

Is there some way to generate a more efficient cross-compiler?

Thanks,
