You could also write (\n are mandatory!):

int main()
{
   asm("mov eax, 3\n"
       "int 0x10\n");
   return 0;
}

Build command: gcc -Wall -O2 -s -masm=intel main.c -o main.exe

If you need to write large assembly snippets, it's better to write separate .S files for GAS or just use NASM. ;-)

see Brennan's Guide to Inline Assembly for more information

1) Try the DJGPP Zip File Picker.
2) You need "v2/djdev203.zip", "v2gnu/bnu217b.zip", "v2gnu/gcc421b.zip". That's less than 10 MiB. (Older versions are usually smaller.)
