There is no infrastructure that can be (re-)used for this.  So no, this doesn't
seem worth the effort.

Why not? It doesn't seem too complex to me. The compiler writes a comment to
the object file, the linker reads this.

If it doesn't seem very complex, please go ahead and implement it:

I am saying this without any bad attitude, there is so many things that would
benefit GCC but they are not a priority for the main devs, so GCC needs as much
help as it can get anyway.

If you are interested, I am sure people could provide pointers to documentation
where you can start from.

The concept is simple, the implementation may be simple but for someone not
familiar with the source at all it's far from simple.

I'll first ask people from the gold linker what they think about this idea and
have any ideas for implementation.

[Bug c++/39437] New: Support for automatic linking via pragma

MSVC supports the following pragma, which can be used to automatically link a
library when a header file is included. This is used by for example Boost.

#pragma comment(lib, "requiredLibrary.lib")

Unfortunately, g++ doesn't support this. Could you add it?

You need either the driver reading the object files or the linker knowing the
specifications for this.

Would that be a problem?
