build your own cross-compiler !!!

So I did a git clone of your gitorious project, but I am failing on the iar2gas with

/bin/sh ./iar2gas < ASM_Funtion.s |
arm-none-eabi-as -mcpu=cortex-m3 -mthumb -o ASM_Function-gcc.o
{standard input}: Assembler messages:
{standard input}:564: Error: bad instruction `end’
make: *** [ASM_Function-gcc.o] Error 1

Is this expected, or did I miss a git mother may I command again?

Trying to catch up and understand where things stand.
