cross-compiled object sizes too big

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
495616 /usr/local/lib/libfreetype.so.1314.0.0.10
462848 /bin/busybox
847872 /bin/bash
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,
Dave
