Sourcery on linux can't build for lpc1768 because of startup code

[sazary]

Hi
I'm trying to build a simple code to run on a bare-metal arm micro-controller lpc1768 from NXP, that is from cortex-m3 family. I'm using Sourcery toolchain (specifically, Sourcery CodeBench Lite 2013.11-24 4.8.1) on Ubuntu 12.04, and I'm using the startup code found in lpc17xx CMSIS library, provided by NXP, in path /Core/CM3/DeviceSupport/NXP/LPC17xx/startup/gcc/.
I enter this command:

arm-none-eabi-gcc -g -O3 -mcpu=cortex-m3 -mthumb ./main.c ./Display/glcd.c ./startup_LPC17xx.s ./system_LPC17xx.c -I ./LPC_17xx -I ./Display -I . -Werror -o ./lcd_test.o

and I get this error:

./startup_LPC17xx.s: Assembler messages:
./startup_LPC17xx.s:126: Error: non-constant expression in ".if" statement

I can build and run this code (the C parts) on windows using Keil, and using another startup file, but again I can't build it on windows in Keil using Sourcery toolchain; I get the same error there too.
What should I do?
This is the part of startup code that causes error:
