 I don't expect everyone to track or remember all the individual features 
as they are added to standard revisions or compiler implementations, and 
details provided by Andreas are useful in determining the prerequsites.

 Indeed the breakage caused in the first place serves as a proof: you'd 
imply the code writer as well the approver should have known this feature 
isn't there in every compiler version supported for building binutils, and 
yet they missed it.

 Why do you think it would be preferable to require everyone to chase 
every time something that has been already determined?

 Why would I need to repeat the same exact details as with the original 
report?  This is just to confirm that the same issue triggers for versions 
other than 8.5.0 (just as Andreas has indicated).  I reckon Andrew Burgess 
also reported breakage with his environment.
