Subject: [PATCH] C++ feature checks: Match warnings more strictly
|
||
|
|
|
||
|
|
Require the word "warning" to appear at the start of a line, after
|
||
|
|
whitespace, or after a `:`. This is the same that CTest launchers use
|
||
|
|
to match warnings. It avoids matching "warning" inside file paths.
|
||
|
|
|
||
|
|
Fixes: #19019
