Problem linking with static libraries for arm-elf

[Apostol Terziev <stinky at inray dot spnet dot net>]

Hello, All,

 I have a project that targets the phillips lpc2100 ARM7 MCU. I have 
written the startup code and various drivers for the embeded and some 
custem hardware. My toolchain consists of GMUARM 4.0.2 and 
newlib-1.14.0. Everything compiles and works just fine on the hardware.
 My problems started when I decided to archive all the object files in 
static libraries and link from them. The linker simply refuses to link 
to mu libraries. I have several modules like libsys.a, libuart0.a, 
libi2c.a, libspi.a etc.
 Here is the command from my Makefile that assembles the lbs
AR = arm-elf-ar
$(AR) crsv libsys.a $(OBJECTS)
arm-elf-ranlib libsys.a

Here is what happens when I try to link to libsys.a:

arm-elf-gcc ./src/main.o -nostartfiles -nodefaultlibs -nostdlib -static 
-LC:\cygwin\home\Administrator\soft\arm-elf\lib 
-LC:\cygwin\home\Administrator\soft\arm-elf\lib -LC:\Program 
Files\ARMor\eclipse\gcc\lib\gcc\arm-elf\4.0.2 -Xlinker -Tlpc2100.ld 
-Xlinker -static -otest.elf
lpc210x.ld:299: undefined symbol `endless_loop' referenced in expression
collect2: ld returned 1 exit status
make: *** [test.elf] Error 1
make: Target `all' not remade because of errors.

"endless_loo" IS in the librarry. here is what arm-elf-nm says:
