You didn't tell the compiler to just generate an object
module, so it tried to link it with the C runtime (gcrt1.s)
so you could load and execute the module.  Since your module
probably didn't have main(void) {} in it, the linker barfed.

gcrt1.o comes from c:\avrgcc\avr\lib

Try adding the -c option to your command line.

Try avr-gcc --help | more to see all the options available
