Further to the above:
I switched to the toolchain that came with ecos-3.0  
(C:\cygwin\opt\ecos\gnutools\arm-eabi_q4.08\bin) and then the library  
builds. But when building a simple test app serial_1.c that previously  
worked, I get the following (using eclipse Galileo):

------------------------------------------------------------
**** Build of configuration Debug for project serial_1 ****

make all
Building file: ../serial_1.c
Invoking: GCC C Compiler
/opt/ecos/gnutools/arm-eabi_q4.08/bin/arm-eabi-gcc  
-I"C:\ecos\icb4\icb_lib_1_install/include" -O0 -g3 -c -c -mcpu=arm7tdmi  
-Wall -Wpointer-arith -Wstrict-prototypes -Winline -Wundef  
-ffunction-sections -fdata-sections -fno-exceptions -MMD -MP  
-MF"serial_1.d" -MT"serial_1.d" -o"serial_1.o" "../serial_1.c"
Finished building: ../serial_1.c

Building target: serial_1.elf
Invoking: GCC C Linker
/opt/ecos/gnutools/arm-eabi_q4.08/bin/arm-eabi-gcc -nostartfiles  
-L"C:\ecos\icb4\icb_lib_1_install/lib" -Ttarget.ld -Wl,--gc-sections  
-Wl,-static -g -nostdlib -nostartfiles -Xlinker -Map -Xlinker serial_1.Map  
-o"serial_1.elf"  ./serial_1.o
Finished building target: serial_1.elf

make --no-print-directory post-build
serial_1.d:1: *** multiple target patterns.  Stop.
make: *** [serial_1.elf] Error 2
-------------------------------------------------------------
I do not understand the meaning of the last 3 lines - nor how to fix the  
problem. Thanks for help Robert.
