Hi Jeremy, Sorry I didn't get time to spend on the plugin. I reviewed the code, and found that it was a silly mistake. Basically, I had written the plugin for gcc first, and there was a version match check. Since the version is different for avr-gcc than gcc mainline, it was failing there. Essentially, a call to "plugin_default_version_check (version, &gcc_version)" was failing. Thanks and regards, Sandeep.
