Yes, it does! It's a wonder that the committee didn't insist long ago that there be a directive in the language which would pass a name(file?) to the linker for processing. It's not like we haven't been fighting this problem since
the
late 1970s and it's still a compiler specific thing. Kinda makes you wonder exactly what things the committee deems important, and why (we STILL don't have #pragma once as a "standard" requirement).
[Bennett, Patrick] Personally, I think the pragma 'link' options are an absolute disaster for large projects. It's far, far too easy to end up with lots of libraries getting linked in with users having no idea how or why they're being linked against. Since many developers tend to be rather over-eager in #including headers (bah, just include it all!) it's quite common for library x to include library y which happens to include library z. Users then wonder why their application is suddenly dependent on libraries they never even 'use'. Libraries linked against should always be completely explicit IMO (or managed by a build system that documents the dependencies). When the linkage is explicit, the cases where libraries have too many inter-dependencies (usually incorrect) tend to get fixed pretty quickly. Patrick Bennett
