There is an experimental version of avrdude that is completely based on the 
Win32 API and 
not Cygwin. It can be found here (toward the bottom):

<http://www.siwawi.arubi.uni-kl.de/avr_projects/>

It includes all the sources and a binary as well.

This seems to have fixed a lot of other user problems; perhaps it will work for 
you as well. 
There are plans to roll this into the avrdude project.
