	Hello all,

How can I avoid compiling crt0 and related into a simple project?

For example :

int main (void) {
   int a;

   a = 'a';

   return 1;

compiled with: arm-elf-gcc -ggdb -mcpu=arm7tdmi -mthumb -o test.elf
gives: ls -l test.elf
       -rwxr-xr-x   1 belleja  we2        144945 Dec 19 13:13 test.elf

Quite a big size for small code not??

So I wonder how to avoid crt0 and replace it with my own stuff...
