We are, in fact, following the standards. Absolutely. I can't see where not. Yet, we do not *enforce* the standards onto others so that our users can get working programs without having to patch manually (what most of our users can't or don't want to, not to speak from submitting patches upstream). ISO C99 explicitly mentions the possible way of expanding `errno' to "for example, *errno()". And this is what we do. We even make this function inline so that generated code is nice. > To summarize the situation: "extern int errno;" is INCORRECT.

I agree. But with this commit we reduce breakage on our side. Where is the problem? We are standards compliant, but we don't enforce it onto others. That strict and liberal thing, you know? cheers simon -- Serve - BSD +++ RENT this banner advert +++ ASCII Ribbon /"\ Work - Mac +++ space for low $$$ NOW!1 +++ Campaign \ / Party Enjoy Relax | http://dragonflybsd.org Against HTML \ Dude 2c 2 the max ! http://golden-apple.biz Mail + News / \
