Or perhaps a gcc header like the kernel is needed and the value changed to __attributed_used__ .

Hello,

I'm noticing that the examples directory fails to compile with

gcc-3.4.0.

The _exports.h symbols are not making it into stubs.o .

I found that the compile works if you:

Change: static void __attribute__((unused)) dummy(void) to: void __attribute__((unused)) dummy(void)

This would seem to be a new optimization or bug. I would expect that unused should make it stick around, even if it is not used locally.

The kernel uses this same construct in a few places mostly in debug

code

and drivers I don't' use...

Regards,

Richard W.
