Maybe ignore lines starting with whitespace and then "|"?

Yeah... keep on patching I suppose.

In
(info "(gcc) Diagnostic Message Formatting Options")
I see:
'-fdiagnostics-format=FORMAT'
Select a different format for printing diagnostics. FORMAT is
'text' or 'json'. The default is 'text'.
I guess it could be made to work, though to be really useful I think
Emacs would have to reformat this before inserting in the compilation
buffer; but also it doesn't really solve the problem because while gcc
does this, many other tools run by make do not.
