<div dir="ltr">Thanks for asking. I just want to make sure I understand your statement and question. On Darwin, you've always had __weak defined as <span style="font-family:arial,sans-serif;font-size:12.800000190734863px">__attribute__((objc_gc(weak))), even when __strong is defined as <empty>?</span><div>

We can put a comment into the header file for GNUstep to explain why __weak is being undef'ed before it is defined as <empty>. (Without the undef, the build generates seemingly hundreds of warnings, obscuring other warnings that might be more meaningful.)</span></div>

</div>Yes, this is what we've always done on Darwin. Is there a problem specifically?<br>
