Hello,
do the C dialect options -std=* affect the ABI?

For example can I safely link objects produced with different C++ standard
versions to produce an executable?
You started out asking about C but then finish asking about C++, which
are you asking about?
The C++ standard options are also documented on this page. In the text
you have:
"The following options control the dialect of C (or languages derived
from C, such as C++, Objective-C and Objective-C++) that the compiler
accepts:"
For C++ see https://stackoverflow.com/questions/46746878/is-it-safe-to-link-c17-c14-and-c11-objects/49119902#49119902
To the best of my knowledge the -std options for C do not affect ABI
either, but I'm less certain than I am for C++.
I think it should be documented on this page if the ABI is affected.
