[avr-gcc-list] re:avrgcc for window NT with AVR studio3.56 - Gcctest9

[Loc Mai]

Yeh, I almost got through it. But after building project, there is an error
as:
errors: none
----end---
Errors detected during link stage
stopped.

It is not easy to understand makefile, to me.  Any expert can advise me.
Thanks.

Here is the makefile (copied and little bit changed from Winavr\sample)

FORMAT = ihex

# Target file name (without extension).

# (Note: 3 is not always the best optimization level. See avr-libc FAQ)
