Next step in size reduction

Hello everybody and Happy New Year,

I have one of those 'old' h3100 machines that has 16MB
Flash and since some apps become using gtk 2.0
libraries, space needs are growing.

Searching how to reduce this, I've found uclibc that
seems a great help:
http://www.uclibc.org/
uClibc (aka µClibc/pronounced yew-see-lib-see) is a C
library for developing embedded Linux systems. It is
much smaller than the GNU C Library, but nearly all
applications supported by glibc also work perfectly
with uClibc. Porting applications from glibc to uClibc
typically involves just recompiling the source code.
uClibc even supports shared libraries and threading.
It currently runs on standard Linux and MMU-less (also
known as µClinux) systems with support for alpha, ARM,
i386, i960, h8300, m68k, mips/mipsel, PowerPC, SH,
SPARC, and v850 processors.

So, maybe, its use could reduce image size and gtk 2.0
could be use in those 16MB Flash or NAND (like h1910)
machines.

Talking with some people about this, they mention me
the ARM Thumb mode, that doesn't work in StrongARM
(sic) but works for Xscale or ARM7T and ARM9T:
http://foldoc.doc.ic.ac.uk/foldoc/foldoc.cgi?Thumb
An extension to the Advanced RISC Machine
architecture, announced on 06 March 1995 by Advanced
RISC Machines Ltd. By identifying the critical subset
of the ARM instruction set and encoding it into 16
bits, ARM has succeeded in reducing typical program
size by 30-40% from ARM's already excellent code
density.

Wow! 30% reduction. Have you thought about mixing
uclibc and Thumb mode in (for example) new Xscale
devices?

How much Flash or NAND would be needed for
Familiar/GPE2 with those features? 8MB?

A bit off-topic: Which are the differences between
NAND and FlashROM? Which one is better for an embedded
system?

Thanks,
