Details:

Version: Version 5.11-Patch#7610
Environment: Windows VistaSP2
Appears that the Windows environment variables in the form of %variable% do
not work consistently with AVRDUDE.

Example: using %temp%
Specific issue: Reading contents of chip works but writing binary to the chip
fails with a parsing error.  

Manual Workaround: Removing the drive letter "C:" from the %temp% resolution
allows the command to complete without error.

Desired behavior: for command files, consistent parsing of the %path% variable
is required

>echo %temp%
C:\Users\owner\AppData\Local\Temp
