I've started my project in ARM mode by modification of example code for 
LPC2106 and it still remains in my project:-)

yes

yes, I'm using default ld and makefile from examples included in WinARM gcc. 
I've only removed comment character before mthumb-interwork in makefile and 
after this modification my code will crash.
