Lpc2000

Hello All:
	First, than you all for the answers on my previous question about a C union 
not working for IO access. I'm now compiling some programs with GCC 3.4.3 and 
newlib 1.12. I've download the source packages from http://rod.info/arm.html 
and used his build script to build the toolchain. All went very smooth.
	I've been able to compile FreeRTOS for LPC2106 and tried to blink some LEDs 
(hence the question about the C union), but when I try to use any code from 
the newlib, I get the following warning:

arm-elf-ld: Warning: /opt/arm/lib/gcc/arm-elf/3.4.3//libgcc.a(_udivsi3.o) does 
not support interworking, whereas test2.prg does

And a little but further:

arm-elf-ld:   first 
occurrence: /opt/arm/lib/gcc/arm-elf/3.4.3/../../../../arm-elf/lib//libc.a(mallocr.o): 
thumb call to arm

I checked the build script against the GNU ARM page and they both build newlib 
with the --enable-interwork --enable-multilib options. So I though I had 
interwork enabled. The only google reference I got 
( http://www.codesourcery.com/archives/arm-gnu/msg00030.html ) tells this:

"If you do require thumb interworking you will need to recompile both the C 
library (newlib) and compiler support library (libgcc) with interworking 
support."

The build scrip and GNU ARM both build GCC with the --enable-interwork 
--enable-multilib --with-newlib options. So I'm a bit confused: Is this 
anewlib problem, a GCC problem or a compilation problem of my app? Thanks a 
lot!
