I am not sure that this is the right place to ask this but based on my searching this looks at least close.
I installed winAVR on my notebook computer but I obviously did something wrong. I think I had WinAVR working correctly at one point on this computer since I installed Windows 7 on it but I am not sure I really tested it.
I have an application that uses make under cygwin which runs fine under XP on my office computer. Cygwin appears to behave itself until the make calls the compiler. avr_gcc crashes with an error message indicating that it tried to terminate in an unsupported way.
I have tried running the make under the command prompt but that fails with a variable error code. I tried setting avr_gcc to XP compatibility but then it would not run due to "access denied".
