The bug reporter of bug #141015 used exit() on all occasions, I thought that didn't count as a return? (just curiosity) I think the noreturn attribute is quite overkill for normal computers though, this in contrast to embedded development. > I doubt that you want a hosted compiler environment while building code > for such a device.

I looked at the description of -ffreestanding; I'm under the impression you are talking about a program that does not use standard libraries, whereas I'm talking about development using avr-libc. The avr-libc documentation has this to say about -ffreestanding: > However, this also turns off all optimizations normally done by the > compiler which assume that functions known by a certain name behave as > described by the standard.

Doesn't sound like what I want. Thanks for the reply, Peter. -- I'm using the GNU Privacy Guard (GnuPG) in combination with Enigmail. You can send me encrypted mail if you want some privacy.
