This would be great. It also implies we can then move it to
`compiler_attributes.h` since it does not depend on config options
anymore.
We should also rename it to `__nodiscard`, since that is the
standardized name (coming soon to C2x and in C++ for years).
Cc'ing the Clang folks too to make them aware.
Cheers,
Miguel

I can move it to compiler_attribute.h
This attribute is supported by gcc, clang, and icc.
https://godbolt.org/z/ehd6so
I can send v2.
I do not mind renaming, but it should be done in a separate patch.

Of course -- sorry, I didn't mean we had to do them now, i.e. we can
do the move and the rename later on, if you prefer.
Cheers,
Miguel
